Honestly, I'm tired of always knowing about Twitter account hackers like this, why is it so often and the accounts that are hacked are also famous accounts with blue ticks. Either twitter doesn't increase its security level or is it very easy to hack and doesn't solve some hackers.

This is certainly not new news anymore, there have been almost many similar cases since the big incident when many accounts of state officials and famous people were hacked simultaneously.
people who don't pay much attention to the news about crypto and about scamming methods like this will be fooled and it's easy to deposit funds at the fraudulent address.
