*snip*I think 99% of tumblr users feel they can comment on, re-post, re-blog, and re-purpose anything that crosses their dash. This is not limited to members of Loki’s Resistance.
I am unaware of any rule of etiquette that discourages making comments on graphics. I am unaware of the gifset to which you refer, since I avoid Thorki/Thunderfrost like the plague. Perhaps the gifset was open to interpretation? As you say, tags are lost in reblogging, and two characters being physical with each other in a way that shippers see as angry sex, can be interpreted by others as abuse.
I think this is a problem of educating tumblr users in general about preferences of those who make graphics. The maker could post a line stating the intent of the graphic: Thorki gif by (maker). Please do not add comments. Though not all graphics makers object to tumblr users adding comments and even re-purposing their works, graphics makers could try to educate tumblr at large, just as tumblr artists have been educating about properly sourcing art, crediting artists, and their preference for re-blogging rather than re-posting art.
Alternatively, the maker of the gifset in question could have privately contacted the person who commented, and asked for the comment to be removed, without accusing an entire segment of the fandom of aggressiveness and character-bashing.
BTW, someone recently commented on the Frostiron tag that “This doesn’t look like a heathly relationship.” We all chuckled, and agreed. I don’t know for sure, but I suspect Thorki/Thunderfrost shippers are similarly honest about their ship.
Except the thing is, going into a fandom tag, or making comments on a particular ships content is pretty much considered bad form by pretty much EVERYONE. I might not like a ship, but if by some happenstance I reblog it, I’ve had to LEARN not to do the kneejerk reaction of ‘well, this art is pretty, but I don’t actually ship this.’ Just tag it for people’s saviors and move on with your life. I had to learn that you don’t need excuses for good art.
Some people actually don’t realize this is bad form. Letting them know that someone ‘made this thing’ and its insulting to put those comments where the artist can see it is just par for the course. You help them learn what is and is not appropriate behavior.
*edited for misreading part*
I still don’t understand why this has been made into a general Loki’s Resistance issue, when, as far as I can tell, it’s more a problem of general ignorance of fandom etiquette, and the gif maker could have contacted whoever made the offending post directly.
Whatever. Lay all the problems of the fandom and tumblr on our doorstep. It’s a convenient place, and the address is well-known.
