But a lot of people name change for controversial threads, so looking up a poster’s history won’t always apply.
I do think when someone repeatedly asks for relationship assistance & then someone looks at their post history & remarks on the posting pattern, some people tend to be shocked or insinuate it’s “creepy” behaviour to do that.
However, it usually only seems to be when the OP has been caught out in a lie, or is being told their relationship is not a good one, based on all their previous threads.
I don’t think people go looking to check if you said your age was the same in every single thread, as people may tweak those details for privacy reasons.
Isn’t this why people name change sometimes when creating a thread? They don’t want it linked back to their username.
It’s not a creepy thing to do a background check in order to provide a more tailored & comprehensive response. People are taking the time to reply to a thread, so to call them “creepy” because they have discovered an inconsistency seems like a deflection.
