Regardless of whether you are for or against recent changes I believe no images already on the site were removed by the mods, and I’m a strong believer in archival. I’ve personally
been on DNP for ages, but “artist upload only” and when I request takedowns of images I did it’s mainly because I’m ashamed of my old drawings, not because I have a grudge with the site or its policies.
If you’re taking a stand and moving elsewhere I just want to ask that you consider to not opting for full content wipes and choose the same DNP option I did, preserving your older works. This whole situation is horrible enough without losing a large backlog of pony artwork from here. I’ve uploaded a lot of commissions I got over the years - including one from you, Datte, I’m obviously biased - and I would hate to lose those images from here if artists request to wipe their entire tag.
Erasing your drawings only takes a single SQL query and maybe a few seconds for it to execute, you’re not really overwhelming the system and sticking it to the staff. The deletion itself is a minor inconvenience, the real cost is losing a large archive of works off a site that, for better of for worse, has been in existence for years.
The future of any clone that pops up is yet uncertain, and if everyone moves their content off this site to another that’s then shot down for any reason that’s not just a loss for Derpibooru, but the fandom as a whole. If you believe in archival too, by all means upload your works to every site you can find, the more the better, increasing your chances of it staying available for everyone. Just think back to when Tumblr nuked NSFW artists’ blogs on a whim; for many images that was the only source.
The bottom line is
TL;DR Do whatever and go wherever you like, but if I can ask one thing, please keep images already up here up via DNPing as “artist upload only” (the option on the page is “I want to be the only person allowed to upload my art to Derpibooru”) and if you move to another platform keep your drawings on as many as you can (instead of just a specific one) to avoid your works disappearing now or in the future.
