I wouldn't suggest botting imo, and I do believe that they have new detecting technology. I got from around 65-93 fishing around 3 months ago doing it on my pure, and when I botted fishing for only 2 days on my main, he got rollbacked the next day later.
For me, they rolled me back 1 day after I finished botting. I botted, then decided to do normal stuff, and the last thing I did was plant some ranarr seeds. When i logged in the next morning, i was 12 combat levels under my original (was lv 117, now 105).
I don't know when I will be resuming botting on my main, if ever anymore. If I do, it's not going to be on my main, but botting on dummy accounts, and transferring the cash to my main, or selling the gold on Sythe or something along the lines.
