Aww man sorry to hear. Yea that's a good practice keeping your pen name and personal separate.
Yea thinking exactly what @Katzalcoatl said, u prob accidentally posted it somewhere in past.
Can politely tell them you're busy at 1st and if they continues to be persistent you always have the option to ignore them
Haven't got anything wierd on Tapas yet thankfully but the creepiest have to be those on Deviant art, I just ignore them.
Most of the weird ones there are for my oc Adam, had some sexy pics of him there and others of him in combat -but once in a while I'd get disturbing pms from people a little too obsessed with him and they demand things like having his limbs chopped off. The creepiest was someone obsessed with a flash back image of Adam as a kid, it was disturbing so I ignored and deleted.
Outside Art community RL had mostly positive experiences of people recognizing me
Years back I was interested in recording arts made a song sang at a few gigs, karaoke and cosplayed once for a con as Aladdin. So became norm for strangers coming up and recognizing me from one of those.
Only had eek situation was one girl who recognized me from the Aladdin cosplay. It was at my cousin wedding, I had to stay at door to help guests to sign the picture. This was a year after I cosplayed, and there was an anime con next-door to where the wedding took place. One girl remembered me from the cosplay came over, we had a casual conversation about anime and art. Was prob my mistake exchanging Insta contacts. After that she constantly sent sexual messages, I told her I'm not comfortable nor interested in her that way, she continued until I just stopped responding, Wasn't expecting this from her and glad she eventually stopped.
Yea just seems Ignoring is the best method, they'd eventually stop, even if they dead set
