PNV - Banter and General Comments, page-4258

There are trolls on just about every HC group.
Mostly they are non holders and seek to either;
a) negatively influence those researching a stock &/or new holders.
b) stifle valued discussion.
Some are exceptionally good at it, Aloha not so much.

As seen here though, hitting the ignore button is a cludge at best.
It would take quite some admin time & resource to weed out and curtail these activities, particularly when often new alternate accounts are apparently created for this purpose, but it can & should be done else the overall value plummets.
