Why not just program a bot to crawl their site looking for any string that says "lemmy" or "l e m m y" or what have you? I'd think it's be easy for them to do, the bigger question is what kind of backlash they would get for it.

I'd be more worried about martyring lemmy on Reddit which would just force more traffic over here imo.

Or maybe they dont think Lemmy is actually a threat.
