Hello - please don't do this. I'm not in this fandom, but I've been in other fandoms under my wallet name, back when we were all younger and more innocent. I am very, very lucky in that most of my fannish activities can be under my wallet name because I am in a profession that tolerates this. (Freelance writer/novelist.) Even then, I took down my fan vids years ago; for career reasons (I've since done work-for-hire writing for Marvel and Disney/Star Wars, among other things) it would be a bad idea for me to have those still publicly circulating.

There are people whose jobs will not tolerate evidence of fannish activities, even the most vanilla kind; probably the majority. There are people who are dealing with stalkers. As brightknightie points out, it's one thing to keep a downloaded copy of some fic (etc.) for personal enjoyment and another to repost them to the public. Unless you have the explicit consent of the specific person whose fanwork(s) you're reposting, I would not do this. The risk of outing/doxxing someone in a way that they can't control is too high.
