I did not for one minute say that it was. Nor did I suggest any qualitative assessment of good or bad, as you put it. I merely pointed out that as thing stand it seems feasible for any banned user to use GDPR (invoke) and start again with impunity. Likewise, any of the rest of us could erase our past comments should we so choose and come back with no history of our prior comments/positions, etc.
As things stand, these appear to be the facts, without a specific policy being stated to address such things. I'll leave it there for now, unless a moderator wishes to chip in with any actual policy position or update. I do feel that whatever the wider issues, it really is not in the spirit of a forum to erase one's past. Just my opinion, for what it is worth.
