I'm sorry, but Keith is just being... Well, bitchy, here.
The Morrissey Bootlegs community is about sharing and helping others complete their collections. I simply don't know what you plan to get from attempting to stop people from having .MP3 versions.
This is coming from someone who totally understands the considerable difference between FLAC and MP3. Played on a superior system, original CD flac files can sound tremendous compared to MP3s.
But this community is about sharing, not about collecting some sort of personal name and merit for recording the bootlegs. I've made a cover design, seen here:

Now, normally as it's a piece of art, if someone took my art and changed it, I would be quite peeved. But this is unofficial stuff, made in my own spare time, for a community where material is shared. If changes in the design somehow helped some people, like for example someone making the type bigger so that visually impaired people could view it with more ease, that'd be great!
Sharing bootlegs is not about personal gain, egos and name value, it's about giving people what they need for their own collections, and potentially, they will give more back which makes everyone happy. If you can't deal with this, then I really think your in the wrong place.
