Poetry.com will accept a poem 20 lines long and everyone one I know get accepted and told they are a finalist.
They send you a draft to proof and send back and that is all fine and dandy and supposedly it goes into a book of poetry which you will never see unless you pay for the book.
Any company that is on the up and up pays you, you dont pay them.I have sent in good poetry and bad poetry to see what would happen and they all got accepted.
If you want to be accepted for publication on anything you write get yourself the latest version of writers digest in which it will tell you all the markets to sell to, prices, what they expect and so on. You can send quiery letters to some and in other cases you can just send in your work but make sure it is in the form they ask for. These are all well known places and when accepted they pay you.
Dont be discouraged if you get a rejection letter or two as we all do but if you keep trying and market what you write in the right place you will be on your way.
So dont waste your time on these places that want you to pay them.
Many of you I know from other sites are writers and already know about this. There are other online publications for writers outlets and there are some sights online to write for. Be sure you retain your copyright when writing on line and keep a hard copy. If these sights go out of business and you dont have hard copies you will lose all your work as I learned the hard way.
