Hi
I've found devtome credit the words written for them and they do it accurately (rounding the words to the appropriate number of thousands). You'll have to make sure you've submitted any article correctly, creating the appropriate page for it, and listing its link on the devtome homepage and in your profile.
The only problem I find with article writing for devtome is that, although you do ultimately get sent the devcoins due to you, they come to you extremely slowly in amounts of 45,000 a time. Bearing in mind you need to receive millions of devcoins to get any significant 'value' (in terms of the amount of US dollars you can exchange them for), the problem is not so much doing the writing necessary to earn them, but rather the rate at which you will receive them. Your effective income is therefore limited by this rather than your ability to do volume article writing.
Anyway, all the best to you whether you persist with your article writing or not.
