`  :I'm slightly confused here, not least because I haven't received any real warning, and I don't know what exactly I might have done. I have tried to discover which part of WP:HA I have contravened; it certainly wasn't my intention to harrass anyone. I wasn't offensive (at least, I hope not); my purpose was not to make Stho002 (or anyone else) ``feel threatened or intimidated``. I only returned to Stho002's talk page because he made an offer of a paper which would be very useful for resolving the issues at Munididae; as soon as it became clear that that wouldn't be forthcoming, I walked away. I didn't crow, because I genuinely think it's a shame when a knowledgeable contributor gets blocked. I can only assume that this is to do with the comments above about his admin actions on Wikispecies (which were made publicly, but were not ``calculated to be noticed by the target``). I didn't make any personal attacks; I only made some observations in the context of a previous dispute he had with another editor, and that only because I was asked to comment on the article in question. I'll gladly apologise for anything I might have done, but without understanding the block, I can't really appeal against it.   `
