There's been a lot of news lately regarding banning of ICO advertisement throughout Google Ads. It will eliminate advertisement that were misleading and annoying to the public. They are currently working on it and expect it to be cleanse by around June or July. So, I support what you have stated.
In fact, I have a post pertaining to it, which you can see here: https://bitcointalksearch.org/topic/m.32368084
However, we can't blame Coinmarketcap for accepting such placements since the traffic of the site is heavy of crypto enthusiasts and there's no better place to advetise such one but to crypto related content sites. Also, how could you not support it? The statistics being shown there are quite accurate. Moreover, it's a good source for traders and investors alike.
I read that CMC would 'manage' rates and positions for money. Is it true?
