One thing noticed by seasoned webmasters is the clever spammers that post an innocuous message which they leave until suddenly it gets edited into being a conventional spam message (reported on SFS as sometimes being left untouched for years) . That behaviour is made more difficult on OSM since many many folks make just one edit & are never seen again.

I’ve spotted a lot of these nonsense Diary postings. This is simply the latest (the single letter ‘A’). On my own website I simply deleted such users; if they were not spammers, then they were a total waste of disk & db space. However, after 7 months mapping for OSM my anti-spam brain has suddenly clicked into place; these potential spammers need watching. That needs to be done programmatically (links of latest updated diaries crosschecked with original postdates) but in the meantime I’ll assemble a watchlist here (almost all these folks are 0 Edits 0 Traces 1 Diary):—
