Banned without warnings

Is it normal to be permanently banned for botting on a new account that had 0 warnings and 0 suspensions before? what i know for botting u get 2-3 days ban and a strike and the next time is permanent ban or sometimes its a long ban around 6 months or so, but being banned permanently on a new account is this normal or is it their new TOS?

note: i also only botedfor 30 minutes then never botted after that, but the following month i got the ban.

Thank you!
