when people laugh at your posts, what should you do

Report it to Admin.

I just laugh back. Not everyone is going to get you.

Nothing. Something as trivial as a laugh emoji should not be upsetting.

[@merchantofoldeurope] 🤷‍♂️maybe they have a bizarre sense of humour a peculiat irony there are some strange bods on here

Assume they're being sarcastic.

Just ignore them. They aren’t worth the time.

Leave well alone.
Too many nutcases and Trolls out there and trying to engage them is exhausting.
Just mute them

Ignore it. They’re probably an idiot and are just reacting as one typically does.
