But that's not what we are talking about. We are comparing the effort of verifying multiple accounts every few months to buying high quality PVA accounts that have re-verification part of the service OR buying more accounts to replace ones that drop.
If you can't do standard cost analysis of efforts, you should NOT be in IM at all.
I actually can, here is your standard cost analysis of efforts lazy ass:
Option 1 - open accounts yourself and verify them with your own sim cards:
Cost of opening accounts - zero
Cost of proxies to run accounts - zero (they are opened by your own dynamic IP and will always be accessed through that IP, which doesn't raise a red flag because that is completely real human behavior, aka what most users do).
Cost of sim cards - depends on the country, but I am assuming it's $5, which is pretty standard. I know in some countries you can even get for free via promotions or with $1. So at $5/sim you are looking at a total cost of $250 for 50 accounts, which is way more than enough to get started.
Cost of re-verification - zero, because you own the sim cards.
When accounts become useless (and they shouldn't if you know how to spam correctly, which I am pretty sure you don't because you want to always buy accounts to replace the ones that drop), replacing them costs again... well you guessed it... zero!
With 50 accounts per day, even if they are pretty fresh, you can spam at least 100 groups per day (2 per account), again if you know how to spam correctly and not do it like the average newbie does that logins, spams the groups and logs out.
Speaking about effort, yes it is manual work and takes a bit of time (as Inception said just watch a movie and eat a pizza in the meantime to make it more fun). But it doesn't have to... pay someone $50 to do all the work for 50 accounts ($1/account is a dream for college or high school kids) and there you go, no time "wasted". Again this is the lazy way out and if you can't do this kind of work, really good luck in IM.
If you make at least $10 with spamming 100 groups per day (which is a piece of cake and with that amount you should be hitting at least $100/day), you will make your investment back in 1 month and never have to spend money again.
You want me to continue analysis for option 2 as well or your brain can do that at least?
