They do have quality control over written submissions before it can be accepted to the back log. From simple punctuation usage to the wording usage. And they (the writer for submission) must follow certain rules in their writing to make the programmer job easier to put it in game. If there is too much correction needed it simply goes to the bin. Some people think its worth following this rule while some writers don't think its worth the hassle. In the end, only a very small writer who are competent enough can keep up and have some chances of being paid.The lack of trust is certainly not due to a lack of funds to hire writers, and the fact that they could easily make contracts that clearly define the duties of those hired onto the project (or even work by commission on a smaller scale) seems to suggest that perhaps it may be something else - or maybe I'm just silly. Who knows.
It is a good way of maintaining control in terms of quality and I like that. It's just way too slow to have a new dedicated writers to write content for TiTS. And since present writers keep stalling their content and some abandoned it. It's hard for me to think optimistically that the content would flow as regularly as the good old days of TiTS.
And it doesn't help that CoC2 has more updates with new scenes than TiTs update with either just bugfixing and new npc but not much content for sex scenes.
Anyways, these are just my personal views, there are tons of others who still have high hopes for this project. But for me the feeling of passion from each updates back then seems kinda winded at this point.
