Agreed that the tag photography is broken. I think the photography tag is WAY to broad. I think it should be broken down into many such as travel photography, professional photography, fashion photography and many many others.
Step 2: Then with the help of a bot we could comment on posts that use "photography" that it's too broad and is being boycotted by the whales and that whales will be giving big upvotes to people who post in the more specific tags.
Step 3 Find some benevolent whales to start upvoting in those tags.
Then hopefully the quality will move to the tags and leave the spam in the photography tag.
That's my 2 cents ; )
