System removes posts randomly?

It feels like every time I get a rude reply yo one of my posts, and try to quote it to respond, I get a message saying -

Automatically removed quote of whole previous post.

This happens almost instantaneously, and far faster than a moderator of the forum could have possibly read it, so it HAS to be an automated system doing this…
Can someone explain this to me please. that is assuming the ‘System’ does not remove this question immediately, based on nothing??
Thanks in advance!!

It’s exactly what it says: you can’t quote the entirety of someone’s post. Couldn’t tell you why, but you can try removing something from the quote (like the last period at the end of the quote)

Thanks, that is what I was wondering!!
