It's good idea with negative trail, but it should be handled with care, since like everywhere people may use it the wrong way ..Like putting there someone they don;t like for personal reasons etc..People are just people
Haven't seen anyone using my art that way still, and if I do, he will be put on wall of shame for sure :)))

Sometimes my boyfriend jokes me that I am revolutionist and fighter against injustice in every topic in life :) I don't have problem with protecting original artist loud @art-mess.
