What can we do about it? whatever happens to tokens will have impact on ethereum future,
These thousands of different made up tokens don't impact on ethereum future what so ever. Anyone can make them. That's the whole point.
i hope vitalik can do something about it on the long run before more damage is done to eth glory, eth teams need to start removing bad projects
The whole point of ICOs is that they are unregulated smart contracts that can transfer tokens without involvement of any third party authority. There's nothing that Vitalik should do about it.
Only thing we can do is not give money away for obvious scams with fake or anonymous teams. More research you do on where you are putting your money in, more safe you are.
If you want to own your own coins, it's really your responsibility on where you spend them.
If you don't want to be responsible of your own coins, you can try some custodial wallet services, but that takes away the whole essence of cryptocurrency and those can be scams as well.
If you want safety but and you can't provide it for yourself and still want to invest to sales, you can always try highly vetted and regulated IEOs by trusted exchanges that have some safeguards to protect their customers in case of the fraud.
But even if the project is not a scam, it doesn't guarantee that you wouldn't lose ton of your invested money when the price drops.
