I consider that kind of behaviour as scamming which completly fucks up crypto's reputation.
I just see ICOs as scams mostly, it a great shame for very few projects i miss,i can say I only know of 3 ico operations top that were legit and i still believe in.
yes i know your feel about new project are just launched, moreover the team has no reputation in blockchain community/industry.
and based on the data 8/10 are ended with scamming investor, i know because i'm following the news about crypto project with shit service they offer in the front, and if the project successfully with ICO in future after end ico nothing any update
