Interesting debate
Personally, I wouldn't have thought it was that hard to give some user moderators clear guidelines on what they should or should not delete........ this shouldn't be anything they don't like the look of, but should be anything that is 100% spam (like we've had over the last week or so)....
I like BOTF's suggestions about using technology to pull a thread down if enough people report it, but have no idea if that is feasible given the architecture of the RW site.
Either way, something has to be done, and I really hope that the companies who advertise on here (and are paying Natmag-Rodale for access to runner's hearts, minds and wallets) are aware of the issues, and are exerting pressure on RW to sort it once and for all.....
