Hello, this time I want to discuss the problem of contest proposals. (Maybe someone talked about this before but I want to know more)

About 11 months ago, one of my friends zhuky.RLG , djq_cpp and many red/yellow guys sent a contest proposal to Codeforces. But sadly the Codeforces coordinators ingored them and didn't reply in the following 6 months. At last they deleted the proposal.

The second thing happens more than 2 weeks ago, another friend of mine gwq2017 sent a proposal too but sadly the coordinators ingored him too. :(

But on the proposal page it says the coordinators will reply in at most 2 weeks.So I want to know why this is happening? Can admins or anyone tell me what conditions do we have to meet in detail if we want to send a contest proposal?
