Ico has failed
Maybe you can tell him to return all ETH received in funding then, still leave people that did bounties empty handed but at least they won't be prosecuted. At least their names are known as posted above.
Obirum is scam.
Even one of the community manager said: `I didn't get any info from dev side since their stop the comunity manager. Obviously they are big scam!`
The problem with scammers is, they not care about the feelings or hardship of their investors. They not react even if you threaten them. Most scammers even enjoy toying with their victims or stalling them. I now that because it is not the first scam i got into
For vietnamese investors who lost money it is more easy to report the scam. For investors outside from vietnam it is obviously more difficult.
I hope some vietnamese investors are taking steps and reporting them. It would be great, if they could post any steps they have taken.
Everyone who wants to write to the obirum admin (probably he will ignore you): He changed his username on telegram to @tomcrypt
Edit: Many messages i post on the obirum telegram channel get deleted. The obirum admin is spying in there and delete inconvenient messages. If you want to tell your opinion, maybe bitcointalk is better. I also improved my first post a little bit.
