There's already warnings on new posts about how a question might get closed if you use certain words.
However, on Travel.SE at least, we still get a lot of "I want to go to Europe for 3 weeks, where should I go?"-style subjective questions, and "What's the best tour?" and "What's the most interesting cellphone I can buy in America?". These are subjective/shopping/advice/open and are almost always closed.
So, one user, uncovery, suggested Bait Tags (their words), where if people try and tag their questions as 'recommendation' or 'advice' or 'shopping' as some are prone to doing, we could include phrases in the tags along the lines of 'be very careful, read the FAQ, this is likely to be closed'.
Of course, they may ignore it, or just not tag with those tags, which is annoying, and it's also a hack, so I wondered if there was a better way, or if people on other sites have had similar thoughts / attempts / solutions ?
