Lets see - scour the internet looking for pictures that may belong to others. Then purchase the rights to them. Then sue the infringer. Nothing predatory there.
IMHO the new copyright holder’s options should be restricted to a cease and desist order, after all, the original owner had recourse to the same technology to find the infringement and did not pursue it.
I do not condone using other people’s work without permission or compensation (especially as an artist myself), but some of the examples of things they have pursued are hard to defend. This seems somewhat like a private, civil, ex post facto scheme than a legitimate enterprise that protects either the creators’ rights or the general respect for law it proports to engender.
