Safe as far as bans? Or safe as far as account safety?
It has pretty much the same ban rate as RiD and they claim to only have like 8 bans or something since they began.
Account safety is huge, it is probably the safest bot out there because it is open source. It has the security.sex which is like a firewall and anything that tries to send out from the script you have to approve. (Correct me if I am wrong SRL people) It is the bot that most people choose for leveling their mains if they don't want to pay for RiD, but another bonus over RiD is that you can make your own scripts. All of the public scripts on SRL are safe to use, because the SRL Members+ check them a lot and if they were trying to steal your info it would be caught extremely fast.
