I deem it pretty safe, the scripts dont have any keyloggers, and i just put my pass in the client.
Maybe u think its suspicious because they have free scripts, but its just a great bot.
Some scripts are free, and awesome, and havent got any problems with bans or hacking.
Also i got my pin on it, and its no problem so yeah.
And RsBuddy also haves a forum etc, with alot of members, they wouldn't had these if its not safe.
I think i stated my point, conclusion;Yeah its pretty safe, but bans can even happen to the best scripts.
