FAO all community members ... please be vigilant for a serial troll and alert the mods

In the old forum (now closed) we had major issues with a person who was banned, skirted the ban using various names and email addresses and kept trolling us for a long time.
That person returned recently.
We have placed three bans in the last month or so.
Can we ask that you please flag anything you think may be spam / flame wars / deliberately provocative etc.
Do not engage.
Just report it.
Thank you.
