ALERT: ART THEFT

This is an alert for all you people who make (awesome) manips: there are two groups on Facebook (I'm in one of them) who post pictures of wolves and so far I've found multiple pictures from current deviants:
WolfRoad (mainly)
Winter-Bright (if I read it right)
And multiple other deviants who's art I clearly recognize but cannot name atm. I have commented time after time on the photos asking if they've gotten permission from the artist and every time my comment gets deleted or the post gets taken down. I try to keep track of the art because I don't want your guy's amazing and beautiful art to get claimed by someone else. The names of the groups are:
The Rebirth of Wolves
&
The revenge of the wolves

Thank you and please keep your art safe!
