One of the most obvious attempts I'd say!
1) No one is crazy enough to gift away a big fortune to random people.
2) The user is account named "ArthurMaIU89" and has changed their display name to "Vitalik Buterin".
These new scammers are hard at work in trying to beat Twitter and avoid scam tweet detection. If you haven't noticed, the occurrence of scam ETH giveaway replies has reduced significantly after Twitter's algo update.
Even if give aways are reduced on Twitter thanks to their detections, the thing with scammers is they always try to find a different way to achieve the same objectives.
At most they might leave Twitter for a bit, go elsewhere to scam and then return back to Twitter and thus continue with the cycle.
