for what it's worth
Joe2700 and spacegirl2100 are either the same person, or are using the same computer.
This could be relevant, because IF they are the same person, then it could be argued that regulars here are being deliberately provoked by a pot-stirrer.
If they are simply using the same computer, then no conclusions can be reached.
(and no, I don't see anything wrong with checking IP addresses so long as they are publicly on view anyway)
