1. Promoting ANN bumping group is not wrong nor illegal.
It certianly is not illegal, but it's also something that legit projects simply won't do for many reasons, mostly because those who are offering such services are also ready to promote the scams, without any exception. Those who really want to promote the project in a honest way will just run a signature campaign.
2. Buying high ranking accounts is not wrong nor illegal.
True, not illegal but it is frowned upon, and for a good reason. Many sold accounts were used for scam purposes so that explains why buying/selling accounts will usually get you red tagged.
3. If a person was consulting an ICO that turned out to be dishonest, it doesn't mean that he did anything wrong or even knew about the scam. Or with that logic do you blame all workers of Mt. Gox and Blockchain.com for the scams their company did?
Again true, but when you combine that with all the others things he did, it becomes an issue.
By the way, there was no need for you to use a new account just to write all that, you could have just used your ,ain account, Mr Poutintsev.
