Perhaps you can weight the flags of users. Like users who have flagged non-spam content in the past don't count, and people who have flagged lots of spam count

- mkjones 13y agoYeah, we've played with that idea a bit. It doesn't help the sparseness problem (actually makes it worse), and if we took action as a direct result, it would give people the power to DoS content they disagree with. For sites operating at a smaller scale, this could be a good way to surface content for manual review though.
- RA_Fisher 13y agoAre you using elastic net or other things to handle sparsity? Lots of Bayesian priors?
- peterwwillis 13y agoCould you hire people just to review/flag stuff on a part-time basis, ala Mechanical Turk? Or is the problem just not big enough to warrant the time/money investment? I imagine that while spam is annoying, it probably doesn't impact your bottom line in a big way.
