Tyler asks me another question:
"I'm a little concerned about tag spam. Is this a problem on Flickr and other sites that allow communal tagging?"
So I went and did a search.
I haven't found any discussion of it as an issue. Comment spam on blogs and comment trolls, on the other hand are well-known and much-discussed problems; none of the solutions are perfect, but include:
- Registration (know who posts something)
- Moderation (increase or decrease visibility by editorial intervention)
- Deletion (the ultimate in editorial intervention)
- Complication (making spam hard to do quickly and automatically)
Tag spam might be different than blog comments, because:
a) You can't include a URL (which spam needs to do in most cases to be effective)
b) You can't express yourself to others in a personalized way (which most trolls seem to want to do).
So it may be anodyne enough to not really be useful to vandal communities. Just a guess.
