What i Really see here is meme coin project teams trying to trick people into investing in their project by involving Vitalik in some way and banking on the credibility it will give them.
Got it dude. In my opinion, if shiba was using it as an advertisement for its project. I remember when the shiba community was sounding it about so many shiba coins already distributed to the vitalik's address.
That can also attract so much new demand for shiba coin. This time more and more garbage projects were trying to use the same way as shiba.
