I proposed a very simple and effective solution to his malign influence some 6 or more months ago, and other than vekky, nobody else wanted to know. I hate to be the one to say 'I told you so', but the rest of you were convinced that he had every right to post here (debatable at the very least), or else you thought you might be able to change his ways.
Personally, I was convinced you were all living in cloud cuckoo land, and so it has proved. So don't be too surprised now to find him and his toxic brand dominating the forum. As long as you engaged with him, it was as inevitable as night following day.
You were all warned, were you not?
Now we have trollslayer returning abuse with abuse, and firebrand tansy the firecracker cheering him/her on. If any of you seriously think that is gonna advance our cause, you had better think again.
You'd all be better off dousing the flames with petrol.
