Update for ISS application process: I took the qualifications test and needed .80 (80%) which was 40/50 correct and I think I got 37/50. So I definitely did not meet the requirements but I did appeal every answer that I got wrong in any hope that they take my response into consideration when grading. I emailed the project manager and asked if I could retake the test but we will see what happens next. Just to give everyone an idea I applied March 27, received an email to sign a non-disclosure contract on March 29. Signed it 3/30 then received my first direction toward training on 4/9. The project manager has been really quick on his responses so I will come back with an update on what will happen since I did not get the 80% requirement for the qualification test.
thanks for the share. it's a bit rare to see someone sharing update like you

everybody else seems not interested to update their result here
as for me, finally one of my stealth accounts get recognized by ISS. Their email asking me to sign a NDA -> I got it few days ago. From all 6 different stealth accounts, only one account received this email. hopefully I can get into the qualification test from this one. According to your story apparently you needed about 10 days to get into the qualification test. If it's the same for me, maybe I will get my own test at 25-28 April.
Anyway, for you guys who want to use stealth account to apply to ISS because they ignore your original application, you need to be very careful with IP you use to apply. If you use VPN (does not matter which VPN), you need to check if your IP is already detected as a proxy server. After you connect to your VPN, go to these 3 websites:
ip2location.com
findipinfo.com
whatismyipaddress.com
see if all of them return the same location. Some VPN servers do not return the correct country. For instance, your VPN might tell you it's an Australian server, but if one of these 3 above websites tell you it's US IP address, then you should find another server. If all 3 websites above show consistent result, all the same country and same city, go click your IP address number in whatismyipaddress.com. You will be redirected to a page where it tells you general information about your IP. something like this: http: // whatismyipaddress.com/ip/xxx.xxx.xxx.xxx
Pay attention to this part: "Services:None detected" or "Services: Network sharing device or proxy server". If you connect with your original IP, most of the times it shows as "Services: None detected". However, most VPN servers would show "Services: Network sharing device or proxy server" because almost all of them are already detected as proxy servers. I personally believe ISS/clickworker will always ignore your application if your IP is already listed as proxy server. I think this is what I meant with proxy detection technology despite I might be wrong about this. Every website might have different database/detection technology, so don't believe my assumption if you want.
However, even if you dont think ISS have the same detection technology as whatismyipaddress, you might still want to listen to my advice. if your VPN IP only shows as "Services: Network sharing device" (no mention of proxy server), try to sign up using that specific server. why? because at least its still not yet detected as a proxy server. If it shows as "None detected", that's even better. Do not try to register if the IP is already detected as spam (and yeah, some of VPN IP addresses are detected as spam). This is what I did. I try to find VPN server that is not yet detected as proxy server and I make a fake persona based on that IP. For instance, if the IP is based on Johannesburg, then you make a fake persona as a South African in Johannesburg. Your best bet is to find non-US IP address. Unfortunately, it's very hard to find US IP from any VPN provider that's not detected as proxy server. I have not yet tried all US IPs from major VPN providers so I might be wrong about this. If any of you know any trick to bypass this proxy detection thing, let me know.
Make sure you also use real address, zip code, and real telephone number. Just find property selling website in that specific country. Again, using South Africa as example, go find website where south africans are selling properties. Usually they will have information about the zip code and full address. They also will show their phone number. Let's say the address is 35 XXXXX Street, Johannesburg. Your fake persona should be: 37 XXXX street, johannesburg. Modify the zip code and phone number slightly. Write everything down and use that info to register yourself an outlook account as well as a gmail account. Use the gmail info for the registration and the outlook account when ISS ask for your live ID. You can also use your outlook account for both. You might need a real phone number to create a gmail account because they are going to send you a SMS verification. As for outlook account, DO NOT use your real number when you create account. Use the number you write down for your fake persona, they won't send you any SMS verification if your IP is not suspicious.
Hope it helps. I'm not going to say 100% it'd help. Your best bet is to try with 3-4 different accounts. If you want easier route, maybe you can hire someone on fiverr to register the account for you. For instance, if you want to have a south african account, then hire a south african there. Btw, I don't know if any VPS with dedicated IP is going to help. I have only used one VPS and its IP was caught by clickworker (and ISS never sent me any email either for my registration from my VPS)
*Bottomline: I can say I already made some progress with ISS after I created an account using the above steps. My previous stealth accounts did not use the same method. If I pass their qualification test, the only step to do is to create the stealth paypal account which I think supposed to be easy. I will update you guys when I successfully do it.
