Maybe I didn't express myself properly; they weren't inactive since 2015, they started this project back in 2015. They almost certainly used some bumping service as you don't 800 pages thread for a completely unknown project (at least to me) without some push. On CMC they are listed as "untracked listing" while I couldn't even find them on Coingecko. Looks like they gave up yet they are trying with this marketing technique.
Anyway, definitely reporting material, at least last page or two as that's when this new group appeared.
I think I understood correctly, been inactive since 2015, but recently started back up again, right? This isn't really the norm, most projects seem to push it hard when they've just started to launch the most, though as you've rightly pointed out before, some do it to keep up ratings from external websites.
