This is very sad that senior members consider Marinecoin posts as spam without realising why the messages look how they are and why they are so many in number. All proof of promotion ICOs work this way.
Why the messages look the way they are? An AI Engine manages Marinecoin's ICO and makes text suggestion to airdrop participants. After a person makes a post it compares its suggestion with the post to measure deviation and rewards airdrop if there is not much deviation. The AI is a deep learning one and is learning over time to improve its language and grammar. Till then posts will look botted.
Why there's so many posts? A member can apply for the airdrop everyday with 1 post till supply runs out (95% of total supply i.e. 10 Bn is being distributed in this way). So all members may post once a day on bitcointalk.
It's an honest effort that everybody is putting in to earn the airdrops. There's no bots, there's no spam and there's definitely no scam. It's only plain old shilling.
Additionally, there's many Newbie accounts where these posts are coming from. The reason for this is that many of the participants' original accounts were banned for supposedly spamming BCT. Hence they are forced to create a new account to promote the project when they don't get any reply from the ban appeals mail ID.
