Glad I have nothing to do with Twitter.

It's possible we have some.

"Don't feed the Trolls" is always sound advice - though it is hard to live by.

And if you suspect a Russian Trolls - I'd suggest you report that and why you think that.
There are report buttons when you click on a member name so that part is easy.

I'd just say - have a bit more evidence than "Looks like a Russian Troll". Such as links they've posted etc.. When they reach obvious status you'll see members tagging the Original Post that way as well.

You can also PM SiteSupport if you have questions and concerns.

Obvious folks who post malware are removed fairly quickly from the site.

"Watchers"

Right wing Christian trolls have been here but I don't know about the Ruskies.

No but it’s definitely been invaded by idiots that believe that everyone’s a Russians troll. ?

Can't imagine them wanting to waste their time here. It's right-wing influenced websites that are their likely targets, people too dumb to realized they've been suckered and whom they can whip into a frenzy at the mention of the L-word. Anyone who seems to belong here are not the type to get duped. But then again, if you do get the occasional right-wing-nut-job, are they the trollers or the trollees?

I think that is is possible. About a year ago, I encounered several on this site whose comments were highly political, yet did not seem cognizant of typical American beliefs and ways of expressing ourself.

Not sure, but I do know there are some on here who cannot tell the difference between a Russophile and a Russian troll, and if they can't, or they are just plain paranoid, and are afraid of hearing or seeing an opposing view, then they really are not as American or, as Patriotic as they claim they are, because obviously they have not bothered to read the Constitution or the Bill of Rights.
As for people who think that CNN, NBC, BBC is any more reliable of a news source than RT, it is laughable. Parochial culture-centric views are a clear indication of hillbilly-hood. If I see the world in color rather than in someone's narrow black and white view, that is not my problem, it is theirs.

Is Agnostic.com populous and/or influential enough to warrant the effort?

(I doubt it.)

Нет! Здесь нет русских троллей!

I don't know about Russian Trolls, but ALL sites get invaded by trolls, that is just the nature of the Internet and social media, and I might add Homo Sapiens.
