just think when we Reach the limit of Telegram channels And groups or discord servers we cannot join channels, groups or servers on discord or Telegram . So when we participating for Airdrops campaigns we've to add another Telegram or discord account to Gleam and other platforms usually .
Didnt know the limit of group in telegram and discord but if you already reached this level then you can just delete your old group because Im sure they already released the airdrop and you can qualify for the reward already. If you are going to participate for the airdrop, make sure you follow the rules and dont violate it so your effort will not be wasted. Airdrop is more of a luck right now, dont expect too much for the reward.
