Famous Bitcoin developer Jameson Lopp sent an email to his colleagues a month ago warning about a flaw in the Bitcoin test network. Everyone ignored them. Lopp then exploited this flaw, mining 3 years worth of blocks in just one week to gain the community's attention.
If your goal was to attract attention, the plan worked. Both on social media and on sites focused on testnet, several people are talking about the subject. The problem is that no one liked the developer's actions.
“Whoever is screwing with testnest is an idiot and a loser,” wrote Francis Pouliot, founder of brokerage BullBitcoin, before learning who was behind the attack.
