Agree. In these days of increasing scrutiny by federal and state agencies, the so called "pump and dump" is certainly market manipulation especially when carried out by an organized group. This could well fall under RICO laws here in the USA and be seen as organized crime. Crypto is growing up and so must it's users. Attracting the wrong kind of investigation could cost more than any of us are willing to pay.
The price is what it is and should be left to move on the merits of the coin and the project. DGB will gain value soon enough without direct manipulation from unwelcome outside influences.
