Long story short, rdswift had a few additions which didn’t conform to guidelines, and later where he lied about the source, voted down, and he has been loudly suffering ever since.
Even when it was mentioned that his personal image edits could be acceptable if he at least uploaded a original format image as the main image (so that they could cater to the wider range of MB user needs, and not just his own), he could not be bothered doing so.
At the end of the day MusicBrainz is a community website, and not a personal database, so sometimes there is a need to compromise and work together.
MB has a very strong policy of any correct image (and information) being better than none, and no-votes should be used extremely sparingly. I can assure anyone that their additions will not be lightly voted down - in this case it was many image additions and edit notes (and my hours spent cropping out mb-suitable cover art) over a period of time before I started using any no votes.
I can personally say that I was, and still am, disappointed with rdswifts decision not to contribute, which means we miss out on many excellent contributions. But the stance that he has taken, that he will upload NO covers unless he can just upload the ones he wants, and making snide remarks about me on the forums, I have no sympathy or respect for.
I think very few people should have any trouble with uploads being voted down, unless they are completely wrong for that release, so go for it!
