DRKcoin is already above a huge list of a hundred shitcoins that were pumped/dumped and which are slowly dying:
Some were totally uninventive clone coins
Some were clone coins with a small twist to make them different, but without adding anything major to the crypto ecosystem
Some were meme coins that inevitably become less "trendy"
Some were scams
Some were based on flawed economic reasoning (let's issue a few hundred billion coins, like forever, and see what happens)
...so what good did it do for these coins in the long run, that people got "acquainted" with them and then dumped them with a bitter taste?
Additionally how will the community benefit from people that have a 3-day to 2-week "investing" horizon and the constant praise or whine about the prices, depending if one pumps or dumps? These people are like bumblebees who go from flower to flower, expecting to get the nectar (profit from a later pump) and leave.
If you want to be as successful as Bitcoin is, you have to go with its low key approach where people found out about it and appreciated it for what it did and not because it was hyped (instead, it was attacked and said it'll never work for quite a while). Of course I'm not implying that the ROI horizon is like 5 years here, as cryptos are much more adopted right now and things move fast (top20 coinmarket attained in ~4 weeks without hype/spamming/sponsorships etc).
As I see it, the prospect of DRK is not to be a slightly successful coin for a 2 week pump and then die, but rather to become a genuine BTC alternative, if not a BTC killer for certain uses or certain individuals who value their privacy. It's, in a way, degrading for the coin to be treated like a pump&dump scam, creating negative perception.
Don't worry about people finding out... those who are looking at the altcoins are also looking at coinmarketcap. If they want to see why Darkcoin is where it is, and why it will be rising, they can come over here and see for themselves. And those who aren't looking, well, they'll hear what you have to say as something like spamming or, worse yet, ponzi scheme tactics.
It's a fundamental trait of human psychology to value more what you discover yourself, and be skeptical of promises that other make to you - as you are suspect of their motives. So why go against the flow of human psychology dynamics and not have them work in your favor? The only thing that is required for this to work is to have adequate internet presence when one looks you up in Google, ie a Wiki entry, a good coin page, an explanatory FAQ that explains the differences in <30 secs reading - stuff like that. The rest will follow.
