That's because there are some dumbfucks who keep sharing, copy-pasting stuff from there: threads and drama with certain admins etc.
It's those usual bunch of nicknames, if you're here long enough you should instantly recognize them.
They could be:
1) HWZ (SPH) admins who're registered here and trying to shill for their shitty forum.
2) HWZ refugees who still can't bear to part with their shitty forum.
3) Spammers who are registered on both (and probably more) forums posting the same stuff simultaneously. Check the timestamps of those new threads.
