Scrapebox - am i doing it wrong...?

Hi everyone, basically i just want to know if im doing it wrong. I've load up around 3k keywords and tried to do a domain look up. the return was 50 available and the rest are not. I've loaded a proxy found here and check to use proxy also. the results as you can see is suspicious, and tried to do a manual check and some "unavailable" domain in scrapebox, is available in instant domain search or just type directly via browser.

* note

- just learning scrapebox , im new
- just need help , advice or anything

**sorry if i posted this in the wrong section

might want to find some proxies of your own
the better your list of proxies you will get
more results

thanks proxygo, actually i was about thinking of sending you a pm earlier regarding proxy as i've been following your post and i know you are experience and making a living with proxy related stuff. didnt bother though i know a lot will just think im being spoonfeed lol i use the one you posted on fresh proxy list, although i didnt do another ip test with scrapebox cause im base in a third world and net is somewhat slow compared to other countries. anyways im just learning and just asking. thanks!
