Thankfully I haven't had any run-ins of my own with any merverts (don't have a mermaiding FB page yet, no tail yet, no pics/video... Basically no "bait" to attract these types in the first place), but I can vouch that I've seen Craig Bohn posting about his breath hold lessons on the NC Merfest Facebook group page. Didn't think much of it at the time, though I was curious when people had jumped in on his posts basically trying to veer people away from messaging him. Now this makes sense— I had no idea that aquaphiles/breath hold fetishists were even a thing until recently.

If you wouldn't mind, Raina, I could volunteer to help out with any investigative work that may need to be done on future cases, as well as help with compiling lists/evidence and whatnot. "Merverts" are a relatively new concept to me, but I used to do similar alt-tracking and character investigations in a previous fandom keeping track of trolls, scam artists, pedophiles and animal-abusers. I don't imagine this would be much different. :P
