Bill, I am not happy about the situation, however:

I do not think our posts have the protections of copyright.

Secondly, I think the sites that replicated or somehow mirror image us
likely have little going on for them and we lend them credence by using
their names on our posts.

Third, I see no real damages.

Most of our copyright laws protect works or expression of ideas, real ideas,
not postings of likes/dislikes etc.

Therefore, I don't see any benefits other than your signature on your post.
Can I copy it?
