A couple of days I go used the regular OSbot client with dreamfighter. Used a brand new, fresh proxied account. Got banned day 2 after about 20 hours. Currently on my pure I've ran 10-14 hours a day of botting with mirror, switching up between diff skills and what I bot for about 2 weeks now. Also using a main account on a proxy and botting barrows. About 12 hours a day of strictly botting barrows, (on normal client, not mirror). However I do complete elites whenever I get them from chest. I feel like you've got it spot on. I used to think that ban rates were about the script and location however i know dreamfighter is a great script and it didn't get stuck once. I also botted in varrock sewers for those 2 days which is one of the most discrete locations and I didn't receive a single report. However, My friend has ran MTA for 20 hours a day for a week on normal osbot client. He only got banned after using a f2p agility script for 2 hours. And that was only a 2 day Mod ban. I think you're spot on with the new accounts being watched a lot more than older ones. Hope this helps.
