Bubblemaps: MEGA pre-sale suffers from Sybil attack, with over 20 entities using multiple wallets to bypass maximum allocation limits

According to Bubblemaps, Sybil attack activity was detected during the MegaETH MEGA token presale. The MegaETH presale rules clearly stipulate that each user is limited to one wallet, with a maximum bid of $186,000, and identity verification must be completed through the Echo platform. Bubblemaps found approximately 20 entities using multiple linked wallets to exceed the $186,000 limit. One typical case shows that wallet address 0x9f5c received funds through Kraken a day prior and subsequently dispersed the funds to three new wallets, using four addresses to total $600,000, three times the allowed allocation limit.
