:::::Pesky, Penyulap seems to have you convinced that he's incredibly smart, but he's not smart enough to edit Wikipedia without getting into trouble. All of that wall of text about SPI culminated in him pointing at his own newest sock - which he was presumably frustrated that we hadn't found yet. By and large, troublemaking socks are stupid and give themselves away (even if they don't specialise in creating obscene versions of usernames or similar) - and by and large if a blocked/banned editor sneaks back into a different area and edits without trouble, the community isn't mad keen on flushing them out. If Penyulap has this syndrome that gives him a very effective memory in some areas, he may be a bit better at spotting socks than I am - who can often 'feel' a familiarity without being able to pin it down, and that might be of some value to the project. But it's not so valuable that he can be disruptive or create socks himself.
