Hey guys,
I'm Anthony, founder of CoinMarketCal. Some asked the question but there is nothing fishy with the name, we are named CoinMarketCal because we want to be the tool that complements CoinMarketCap.
To answer your concern, here is how the system works:
1) A user submits an event
2) If needed, our team deletes the event
3) If needed, our team edits the event so it looks as professional as possible
Some of the rules: It needs to be unique, from official sources, dated and basically scam-free (photoshopped proofs and fake airdrops are good examples)
You were referencing the XCP event and the fact that they didn't deliver anything. I didn't follow the story but if it's true then I'm sorry to hear this. Please be aware that we cannot control the devs' actions. Just so you know, the event seemed legit for a huge majority of the crypto community (as seen by the votes and Twitter).
A few months ago we added a Report/Edit link so people can quickly contact us if they are aware of a scam. The link is just under the filter on the homepage.
Even though we are trying our best to get rid of scams and fake news, please do your own research.
Hope it helps!
