Aliasing tumblr -> invalid_tag.

Reason: This is fairly meaningless unless it's supposedly an artist attribution, which could simply be mentioned in the description... it's not really that helpful. What most people seem to mean by this is ask_blog; that's about 90% atleast of the images uploaded.

Mods may want to just flop anything tagged with 'tumblr' right now over to ask_blog and I (and maybe other users) will go and weed out the things that are incorrect.

Sound good?

Meh not sure about this one, I personally tag it when I see those blue-ish parts with the question of an user on an image.

I disagree. This tag is used when you see what Butters described so it's not meaningless. Also, I know for sure that there are users that want to search images tagged with tumblr for comic relief, so it is helpful

Cannot support due to what Butter and Husky mentioned.

I like it to remove the pony ones from searches (except john joseco whom I look up by that tag) since most are just attention whoring :P

It's like 100 - 20% = 80% pony, Cam, under that tag. Atleast on the first page.

There is also, of course, stuff like this under the tag:
