what does this mean?

this was one of my old mutuals, they just randomly disappeared and then i got curious and tried looking for their profile through dms. am i blocked? i tried searching them up with my other accounts, but couldn’t find them. if i was blocked, wouldnt it say “account not found”?? i’m confused because this happened to me before with some other account. (you could still see their user, which is why i covered it)
