I'll gladly answer your question but first can you define what's enough by your standards? Because if you are just asking me a two year ban on signatures and a 60 day ban on posting and sending pms is enough for a user to learn his/her lesson after being given a second chance. The duration of the said bans will also show us if the member is really here to be active in contributing in the forum again or just wants to be here to earn money.
