Furries are just people with an interest. Some of them take it too far, but people do that with everything. I saw a lady on TV once that was horny for the Eiffel Tower. In fact, watching TLC makes most furries seem normal by comparison.
Harassment is against the rules
posting one VM isn't typically harassment, nor are there any other rules broken that I can tell.
My personal rule with VMs is not to do much except in extreme cases, such as posting someone else's personal information or graphic images.
