User blog comment:JadenLan/Jaune bunny emblem stolen by someone on tumblr/@comment-5414218-20160305234343

If I was you I wouldn't care that they are using it, but being accused as a thief is plain retarded from their part and I can understand getting mad about that.

You are the one who made it so you have the tools to prove it. You have the comment where you originally posted it with the exact date and time, you have the original photoshop file(I presume) where you made it. If anyone utters stupid shit against you, blast them with the evidence on their faces.

Also, contact the one that originally posted it in Tumblr. Was his/her intention to steal it and claim it as their own? Or were they just posting it with no ill-will?
