I've spotted two airdrop scams that take other projects name claiming to do a new ICO/airdrop and asking for money:

"Tierion ICO": https://bitcointalk.org/index.php?topic=2557841.0

"Click Sense ICO": https://bitcointalk.org/index.php?topic=2558330.0

Both are similar, fake telegram group and twitter account without relationship with original projects.

Hope it helps.
