This is true! I was runecraft botting and my bot some reason opened the Price checker and bot didnt know what to do. I found it and closed it, continued bot for an hour, then banned.
I have had two accounts on different days now banned at 6:30am UTC and 6:50am UTC. Which works out to be 7:30am and 7:50am in UK which is where Jagex is located. I assume they like to keep up to date with bans early in the morning by scanning over accounts.
Who else has been banned around this...
