maybe the offending individual comments are removed DE..? I am hazarding a guess, sometimes its annoying when an entire history of comments are removed, particularly if the user had been helpful at some point in their time on AB
D'you remember when dot hawkes got zapped ?
There was a loss of something like 25,000 answers (a very great many of which were immensely helpful, in the genealogy section) to Answerbank.
I suppose the Eds may take the view that just as the helpful posts of people who no longer visit the site remain in perpetuity for others to read through, suspended-users may have contributed something positive to the site (despite themselves, in some cases)at some point...........
I don't understand a lot of things but I don't mind as long as profane/abusive postings are removed and I have no problems with users having multiple names (and there are some on this thread) as long as they don't make it clear they are fooling us.
I have noticed though that lots of posts from perma- banned users (eg TPFKAK) are still on here.
