  == Re:Edits by 81.19.57.170 ==  It was edits like this   that made me think 'this is not simple vandalism'. Some of the other edits like  , at a quick glance didn't look like vandalism either. On closer look I can see how they can be seen as unhelpful edits, but blocks in response to AIV reports are usually only for clear, obvious, 'right now' vandalism.  As to how to deal with editors like this... It can be tricky, and the response depends on the balance of good, bad and indifferent edits. If there are a significant number of good edits, might be best just to keep a good eye on the contribs and revert the bad ones. If you find yourself continually reverting the same bad ones then a block for disruption might be in order. That may or may not have the effect of getting them to discuss things.
