For best results it's good to take multiple breaks per hour so 20-25 mins per session and any amount above 5 minutes breaking. Use mirror mode, I haven't used stealth in 5+ years it's not as good as mirror.
Personally I haven't received a ban in months, my last ban was during last prime season because I was greedy and overbotted, other than that it's super safe these days, got 8 accounts running as we speak, 2 fighter 2 fisher, thieving, runecrafting and a private moneymaker script.
Location also matters I highly recommend botting in the crabclaw cave on low pop world especially.
As for logs I believe anti-crash feature is causing issues, I'll post another update for that.
Also guys added a couple patches to crabs including the new copy inventory button to make life easier, and a couple stability updates.
Also added some maps including skogres, evil chicken lair (black dragon killing), mos le'harmless, will be adding more locations especially slayer ones since they seem to be popular these days. Fixed some issues with setup window + selecting equipment (banking for equipment too) and a bunch of other stuff.
