Hello,
This is expected behavior. In the settings you specify how much each user will receive.
To revert an airdrop is easy. Every airdrop is assigned a unique tag. You can do this:
1. Backup your database.
2. Log on to your MySQL console (or phpmyadmin)
3. Find your transactions table. Normally it is wp_wallets_txs if you have the standard wp_ DB table prefix.
4. Figure out a row that corresponds to your airdrop. It will be a recent row with category='deposit' and tags “airdrop” and something like “ad-5af46085d815d”. This is the unique id assigned to your airdrop.
5. To delete the airdrop given as an example above, do this:
DELETE FROM wp_wallets_txs WHERE tags LIKE '%ad-5af46085d815d%';
That’s it.
