(I couldn't use the alias tool since they were already aliased to each other)
Size_play has over 300 posts, but it looks like it is being used to mean size_difference with a splash of macro anyways. I'm not sure how they are supposed to differ, but it doesn't seem like they do.
Alternative: If we want to use it as an umbrella term for micro, macro, etc. then everything should probably be implicated to it instead.

Somewhat unrelated: Age_play only has 21 posts, and it looks like they are all just literal age_difference. Does anybody know of similar tags that are used for roleplaying-type posts? (adult characters in a crib wearing diapers, etc.)
