I've been unable to submit aliases because of the bug, and they've been piling up. So I'm going to list some potential ones here, for discussion. Do you see any obvious problems with these?
1) piledriver → piledriver_position
I'm aware that the latter is unused. But this would standardize the tag, since most sex positions are under *_position. In any case, something needs to be done to separate this from the wrestling move.
2) wide → invalid_tag
There were a lot of images in it, before I cleaned it up. I suppose the alternative would be to alias it to wide_hips, since that's how ~98% of it was tagged. Though there were one or two widescreen and wide_eyes.
3) multi_limbs → multi_limb
This might be a good umbrella tag for multiple_arms and multiple_legs?
4) wide_eyes → wide_eyed
Any need to keep these separate?
5) ear_fuck → aural_penetration
Seems same to me, and ear_sex is already aliased to aural_penetration.
