The bulk update request #3535 is pending approval.

create alias same_size_pred (1) -> same_size_vore (5896)
create alias same_size_prey (0) -> same_size_vore (5896)

Reason: These tags are completely redundant, there's no scenario where a post would contain only "same size prey" without it meaning that the prey is the same size as the predator and vice versa.

The same_size tag is also pretty much useless, while it's mostly used as a synonym for same size vore, there have been a few non-vore posts the pop up under the tag from time to time (although what the uploader/tagger is trying to describe as "same size" isn't clear). The tag name is also pretty vague, so an alias directly to same size vore seems inappropriate. Should it be aliased to invalid_tag or re-categorized as invalid?
