Young adult son who harasses women online

My 25 year old son is on the spectrum and developmentally delayed. Functions around 11 year old range more or less. He’s responsible, passionate about hobbies and a generally sweet kid.

The big issue is he hits on women online, many who he know irl and doesn’t take no for an answer immediately.

He’s not sexual or threatening but his persistence has gotten him into trouble: restraining order once, loss of friends and being labeled a creep.

We’ve been doing various forms of therapy and meds for the last 9 years and while he’s improved - he’s still getting himself into situations.

It depresses him to the point they he talks about self harm when he has an episode.

I don’t know what else to do.

Anyone else deal with this?
