It reminds me of when I first started to post on here.
It was after the mostly N/C site I used to follow and occasionally contribute to, closed down.
Someone suggested moving to this site, which I'd already registered on some years ago, but never posted on.
So I did.
It didn't take long for someone I'd inadvertently upset decide I was a previous nuisance, back under a new name.
It seemed best to ignore it.
I just treat any post for what it's worth.
Some make for good debates others don't.
Some are of interest.
I find the best way to treat any WUM is to ignore them.
