Stellar Tried to Give Away 2B XLM Tokens on Keybase. Then the Spammers Came

For the partnership with Stellar, Keybase users could receive tens of dollars in XLM with each airdrop. Malicious usage started right away but it accelerated, Krohn said, and by the November airdrop it was already a serious problem. Eventually, the airdrop on Keybase attracted so many spammers that it was no longer worth trying to continue.
