Final verdict: Foreigners from a telegram channel based about bounties/translations.
Ok, now I'm convinced they are not from 1 telegram channel, they are controlled by 1 person, otherwise they wouldn't be registering one after each other, you would see 2 people registering at the same time at least a few times. Now, another bounty I'm running Bitgoals. 190 related accounts have just signed up, controlled by Ekram account as well. https://docs.google.com/spreadsheets/d/1mHRId-ZxQQXQAjKZtTeqCTMorDFeL2QOp2kk4Lol9OM/edit#gid=985758757
Check the spreadsheet. It starts at 20/06/2018 5:55:45 I can connect those accounts with transactions but I'm too lazy right now and I don't have time either.
