If it's of concern, report it to the mods by clicking on that little triangle to the left of the black strip under the post.
I noted a post in another sub-forum here the other day by a brand new user that simply was a repost of what another had said almost immediately above it. I didn't report that one on the supposition that the poster had intended to quote then comment, but had lost their way.
It could well be someone hacking into the system.
