I just have started answering one of today's questions before wanting to link a related existing answer on this website and falling on this user's profile.
First of all, I never had an interaction with that user or knew his existence before a moment ago, so please do not consider my post from any negative stand point.
I read some of his answers and comment: they are interesting so I am shocked that he is suspended for 11 years (!!!)
Surely I am not competent to be a moderator and I do not pretend to be one day better than them in this job, however I wonder if it is not too severe to block him during more than a decade and prevent people from learning from him especially that 4 days ago he logged back (a sign he would love to be active). I think in an extreme case, a user can be banned for one year at maximum because no one is a terrorist here, all members register to learn and or share their experience and help.
