This was to be expected as the ICO market has proven terrible for most investors, and now people are seeking help from the centralized entities because they're plan to get rich from decentralized projects and tokens didn't work. If it was indded a scam definitely seek justice, but if the case is against a project that is delivering on track and the cryptoasset is performing poorly because of the bear market, you should definetly recosinder.
Do you have a source?
I'm not surprised, though. Most ICOs are completely scams - they plagiarize a whitepaper, make a fake team from stock photos, and put up an Eth address, and that's it. Can be done in under an hour. And yet people are still stupid enough to send them their money. Good luck opening a lawsuit against some anonymous scammer, however.
