Not surprising. I played legit on my main on osbuddy and I got perm banned.
You probably traded and came in contact with a bot, and eventually got flagged.
You probably got ratted. Obviously you tried downloading some fake bot.
I also have checked the source of ultrabot and it is possible to hack your account without the authenticator.
Next time please follow the instructions on bug report.
I've pushed update for v1.12 for that fix. I also have reworked several parts of the script to produce better transitions between both places.
I have tons of accounts banned on home ip and main was never banned. Main was only banned when I botted on the main account.
Back to the question, if you are afraid your main would be banned. Just use @Token proxies.
Going round the bush and not revealing the "well-known seller". Who knows that "well-known seller" might be phishing every person who is using the script?
