The 3 Rules of Fandom... It's such a shame that those have to be stated outright rather than simply being understood as courteous behaviour. OK, there have been wank and shipwars since I don't know when, but even the people engaging in those had some vague understanding of what was expected behaviour. (Probably, anyway.)

I wonder if this is a generational thing (younger fans as opposed to older fans) or a platform thing (a Tumblr fandom problem rather than LJ/DW issues). Or did the rules always need stating and nobody did so before now?
