No, someone isn't going to pay 10.00 sell an account for 50 and recover it back in a week. The 100 posts isn't for "trust" it is to let people learn around the market and reduce the amount of leechers.
Yes that script is clean, trust me it isn't OSBot, this website isn't broke and in no means needs a few mill, it makes plenty.
You need to think about what else you've downloaded, not just recently, if you have a rat it could be from months ago.
Just because you downloaded it "most recently" doesn't mean you weren't already infected by another bot or private server. Phishing links in your email or a link someone sent you via skype are all signs of you being scammed.
We have no access to your passwords.
Could you please link the local script you are using here.
