So, while I wasn't the one that removed your posts, obviously. Moderators do tend to see that a lot of users are reporting in spite rather than because they've happened upon the post. However, that doesn't change the way we handle it. If the user that's the reporter is correct, and the poster is violating the guidelines, then it'll be removed all the same. However, we don't just assume that because a user has a grudge against a user, and has been right previously, that all their reports must be correct.
We review them on a case by case basis. There's plenty of reports that get made each month that are marked as bad, and quite a few of of them are from users just reporting a user simply because they disagree with what they've said.
