Who can tell me? i joined twitter airdrop (registered on gleam.io). but now i cannot join discord airdrop (email already in use). I can join only one airdrop. Yes?
Of course you can only once take part in the bounty (air drops) Rules prohibited. To be honest, I thought it was obvious. 1 account per person, respectively, 1 time can participate on 1 computer.
If so it was possible to tie a lot of accounts, then the whole essence of the air drop would just disappear, this is the right decision from the team, 1 user = 1 account

This is called fraud, and such actions should be spotted as soon as they were discovered. Perhaps the developers and development managers have foreseen this moment, for this very reason, they are asked to install a CRUX wallet on the computer, and provide it in the form upon registration, thereby it will relieve everyone from multi-accounts.
The main goal of bounty or air drops is to attract many unique users who are interested in the idea of the company. Many people on this forum are ready to do everything for the sake of profit, profit and money. It is a pity that people are driven only by money, not something holy.
