1) watermark you images
2) send a formal cease and decist letter to the other parties
3) mention in your ad that these are your own actual pictures
4) hire a professional posting service to keep your ads visible
5) quality will sustain in the long run and your competitors who use stolen images will move on to another opportunity. Let a professional poster handle your ads and try not to let what you cannot control be so upsetting (easier said than done) |
