no but you will have bitcoins ads beeing ads with countless others, but bitcoin will lose the support of the people.
What you say here makes absolutely no sense.
Second, bitmover is right.
Those coins that use bumping services on bitcointalk will never take off.
Most of them are simple ICO scmas that are interested only in raising some money, they put a"roadmap" which effectively shuts down anyone criticizing the project till 2019 and by that time nobody will remember the scam.
Actually those crap coins and tokens are doing Bitcoin a favor, showing to the entire world that we don;t need another coin and making them think twice before investing in an ICO.
And I wouldn't be worried about losing the attention of people, those who really get involved and invest in scamy projects are nothing to cry over.
