According to Keybase's announcement, this month will be the last round of airdrops. The last 100 million Stellar Lumens (XLM) will be allocated to all eligible users within a week starting on December 15. After the completion of this airdrop, the total airdrop will reach 300 million XLM (about 16 million US dollars). The announcement pointed out that starting from around last week, a large number of fake real-life accounts began to flow in, far exceeding the filtering capabilities of Keybase or Stellar Development Foundation. Rewarding these people is not in the interests of Stellar Networks; it is not in the interests of Keybase to make them users of Keybase. Therefore, the Stellar Development Foundation decided to suspend XLM airdrop activities in advance.
