Does anyone else experience this with their Facebook or Instagram accounts?

So I'm sure a lot of us have either Facebook and/or Instagram. Now because of my need for diapers I followed Northshore because I love their mission to end the diaper stigma plus a couple others just Incase they make a new and improved product. Lately I've been getting a lot of Friend requests and private messages from ABDL, I have nothing against them at all, I've met some IC folks who are ABDL and they're pretty alright people, I mean I wear diapers all the time and yes they are very comfortable. However recently this one guy who's never met me comments on one of my posts, I keep most of my stuff private but this was one about a school I graduated from and openly asks if I'm into ABDL. I deleted the comment and blocked the account, like c'mon man, even if I was did it ever occur to you that you don't go on someone's page and blurt that out openly. Am I the only one who's had run in's like this.
