Some 'girl' on facebook was promoting 'her' youtube and facebook page. at the start I was totally oblivious to the fact it was a catfish account. We got into arguments. Mainly me criticising 'her' language and attitude because 'she' was swearing at me and calling me names. But after being able to do copyright legal stuff. I got an artist to copyright his logo and shutdown the youtube channel.
After that the 'girl' got angry and wanted 'her' followers to spam me with hate messages. I quickly avoided this by changing my facebook URL. Then later the facebook account was shutdown after a month. I had downloaded many of 'her' profile pictures in case 'she' changed name or identity etc.
I don't know why, but I didn't think of doing a google image search until a month after the account got closed. I managed to track the images down to the source. Turns out the pictures belonged to a transgender woman's instagram. (obviously the name of the facebook did not match the one on instagram). That was when the lightbulb moment happened. The guy was catfishing to promote his youtube.
All in all, this guy was sloppy. Did not even attempt to cover his tracks. His youtube is still closed at this moment.
EDIT 1: the guy started catfishing again about 4 days ago. Already reported it for being fake.
