For example, Konios bounty has telegram campaign. Just now i checked spreadsheet and found some fake accounts:
(Number 8511 in telegram) https://bitcointalk.org/index.php?action=profile;u=534446 - register date in spreadsheet is 02 april 2018, but last active was July 16, 2015
(8515) https://bitcointalk.org/index.php?action=profile;u=1596663 - same
And also too many fake accounts. "Proof" post solves this problem.
