@cheetah is a bot that only notifies that the content has been found somewhere else and it always includes a link to the content.

If they're reposting their own stuff, then they own the copyright. So, nothing to worry about. But, if they've outright stolen someone else's content as this article talks about, then there's a much higher possibility that they'll get noticed, flagged, listed on the @steemcleaners report, and become liable for a DCMA violation and/or a cease and desist order from the person (or group) whose work they stole.
