FUD attack vectors:

If dev speaks of the plans => he is a pumper
If dev doesn't speak of the plans => he is profiting from inside knowledge when there will be the eventual release, that only he knows about, leaving investors in the dark so he can acquire himself and the whales and then dump on the late-arrivals of investors, etc etc.

Likewise

If dev discloses market moves about his coins => he is a pumper/dumper based on what he discloses
If dev doesn't disclose market moves about his coins => he is a pumper/dumper based on inside knowledge

If coin name = darkcoin => "haha what a ridiculous name, who will adopt a coin like DARKcoin"
If coin name = changed from darkcoin=> "it was rebranded to wash the scam"

If code comes first, papers later => "where is the paper? This can't be serious without a paper"
If paper comes first, code later => "a fuckin paper? this is a pump based on vaporware"

No matter what is done, the trolls will always find something problematic
