This used to be a community of artists that helped other artists in improving their works.
How can you improve if people don't tell you what's good and what not in your work? Do you really think that people faving your works like it? Seriously?
People can drag and drop deviations without even opening them, they just have to drag the thumbnail.
Some are doing it cause they like your works, some are doing it simply cause you're their friend, others are doing it cause they want you to check their profile.
Then again this isn't anymore a community... it's just another social network filled with people that post random images, most of them are far away from being called art.
Enjoy your favs just like I'm enjoying the few comments I receive.
