Im not for sure what method but if you look on RS right now they are doing alot against it. Personally, I autoed for a while and NEVER got caught, warning or nothing. You just gotta know what to do. =)
If you are banned at all using Scar then it is most likely your fault. I have never been banned using Scar and some of my progress reports are 8+ hours on 1 character. Just auto on a character level 20+ with some kind of armour on with a good script. If you don't understand a script then don't use it.
Yes, if you bot with 100 accs at the same time and get caught selling RSGP for real cash tons of times.. So they don't ip. ban people that use SCAR. I think this thread should already be locked because this is quite old..
