nothing is plural here why would I use were instead of was ?

The closest subject is 'we' which corresponds with 'were'; if you want to refer to the page again, then a new subject needs to be inserted here (e.g., using 'it was').

well and were never looked at by a human reviewer. doesn't read well to me at all.
Instead how does this sound as it is a much better subject than we and we are fine, but the page was not?

Since the title of our page is `Pidgin Instant Messenger` it got auto taken down by the AI due to the use of `Messenger` and was never looked at by a human reviewer.
