I don't know but there's one at the end of yours lol.
It started happening a few months ago and I'm yet to learn a definite answer; it may be that they appear wherever the spelling/grammar check on this site believes it detects an issue, for example in your post it has appeared immediately after you repeat your question mark ??..
I had a post full of them and when I corrected my punctuation they seemed to mostly disappear. Mayhap the AI is a control freak and needs al-anon.
Thanks for the explanation MissM! Funny how it threw one of those into my post! LOL. They drive me nuts - I just want to rip them out of everyone's post - LOL
