Is desuarchive a valid URL source ?

I’ve been uploading edits posted in /mlp/ in the last few days, hence the question.

Do files there expire? So long as they don’t, seems fine.

Well its an archiver of 4chan posts. It has more of an incentive to keep things long lasting.
But do you think I should source from other boorus like twibooru instead, if its allowed I mean ? They usually upload anything made in /mlp/ really fast, and its much more focused on image archiving.

twibooru wouldn’t be any more of the source than here, in that case. If desu’s images don’t expire, then it should work as a source, otherwise, it doesn’t really have a “source” anymore…

@Background Pony #5D91
Perfectly valid imo, and unless the artist posted it to another booru as well, Desu should be taken as the main source.

(Though I’d imagine Desu would still be the primary source even in most of those cases, generally being the original upload)
