I just came across this:
Item: Booru syncer.
Description: This will keep your booru up to date by syncing tags and images from booru's that have API support such as gelbooru, danbooru, konachan, etc. For example, if you wish to have a k-on booru the syncer would sync 15K images to your booru then afterwards hourly scans for new pictures. The syncer has an max of 50K images for the basic version and 250K for our paid version.
Price: 20$ Set-up then 6$ per half year.
It's from a place calling itself "Booru Project".
The owners are effectively making profits from Danbooru's community efforts, and are wasting bandwidth and server resources without giving back anything at all.
Thoughts on this?
