GBX (not in that hackernoon list above) goes an extra step though (they are calling them token offerings still, it vets investors and then ensures they are matched by min amounts etc. Yobit even is doing IEOs but they're slapping an old product with a new name (useless internal token, buy low sell high gambling game is what it really is!).
We'll be seeing quite a few Asian ones coming up too, I don't think they'll be good value in keeping track as they're not all going to be as safe or any better than ICOs as portrayed.
Maybe the Asian IEOs you refer to that will come up in future might not be worth tracking as you say but all in all it would be an idea to keep statistics showing failures, successes and scams so the ratios between the three along with geo-location can be used as a tool to identify what is really going on with IEOs
