spam and tagging

The unfortunate thing about spam is that it's easy for one person to generate, but it takes the entire community of non-spammers to fight it.

I get a flood of email spam to my domain and to long-established accounts, right now I have over 3000 spams since my last cleanup in May.

The spam load on my blogs so far is fairly light and easy to clean.

The ILI2005 wiki got spammed, and the IL2004, but only once each, again easy to clean once detected.
I basically have to watch the wiki change feed and check each change.

Even the RSS aggregation feed got spammed, some postings to a bunch of identical spam blogs, full of keywords, one phrase of which matched my running search.

I have also read, but not experienced, about recent Flickr spam.

So I guess my doubts about tagspam (spat?) are probably optimism, it is probably inevitable that there will be spam in the folksonomy.

delicious has rolled out a new "for:" tag, which lets you direct your bookmarks to particular individuals.  As already pointed out in the comments for this feature, this seems like a tempting venue for spam.

I don't see how we can really combat this other than by having good tools and by working as a community.  Having good anti-spam laws also helps.
