:Let me help you out a bit here.  You clearly have read that there are exceptions to the 3RR rule for vandalism, and this is certainly true.  HOWEVER, what you don't seem to understand is how this exception works in practice.  Anyone can call someone else's edit vandalism.  However, if you're invoking the 3rr exception, the vast majority of wiki editors need to agree with that what you're reverting is vandalism.  And generally, anyone who has been around long enough to accumulate more than a few dozen edits isn't going to commit obvious vandalism.  Another pro-tip, claiming you were right in repeated unblock attempts is the fastest way to getting talk page access revoked for the duration of the block.  If you still don't believe that you made a mistake, then it's probably better to just sit out the block in silence....
