Annoying Social Media Habit?

[Maddy]

I have a guy on my Facebook, Twitter and IG. EVERY single thing I post he likes or comments on it. Twitter, he favorites every single thing I tweet(even when they are tweets to other people). Instagram.. likes every single picture & has to comment on every one of them. On Facebook if another friend (not a mutual friend) posts on my wall, he likes it, likes my comments and joins in on the convo even if he doesnt know what we are talking about. Same thing on Twitter.. He's blowing up my notifications. Note, I have never met this guy.

Is it normal to be annoyed or am I just being a b**ch? I put him on restricted on FB but if someone posts on my pg he still joins in on the convo that doesnt involve him in any way...
-Im not a teenager btw.. lol He's about a yr older than me...
