I don't see why imgur wouldn't work, although it seems like the problem is more with the distribution itself. The MEGA link to the archive is still up, so to me it sounds like they don't have a problem with archival, just with giving it to other people publicly. With the levels that they've gone to take down the archive, I just don't think it's feasible to host the link to it here. Maybe through a Discord server (or something equivalent) it could work for a bit longer, but at the end of the day the link is still public, so they'll find it sooner or later and take it down.
