Wow, you don't even pretend to cut them any slack. You might go a little to overboard with the firing back, in some areas though.
Then again I can't say my experience with the FFML or FF.net is much better. It usually goes along the lines of open/search series category, lightly skim them and find that most aren't worth even a few seconds and a significant portion of the remainder you have to put up with substandard writing and a simulated universe that has only the most tenuous connections to the source material.
If they aren't trying to turn it into a fighting game with pointless and unnecessary mini-essays about how powerful and great they *cough* *cough* I mean the character is, it's something sexual, and all to often both with certain fan bases despite such actually going against the spirit of the original source material.
For the record most of my experiments in writing are crossovers, and I never go so far as to finalize anyone ever being with someone else. In many ways I think they can be more legit as you can take the two deep fuse (basically weld the two universe together to best effect, and recompile the characters in the new universe for best fit (my trick, my definition)) them and now you have a legit new story to operate with. Unless the universe is literally setup for it, there's a significant tendency to use author's caveat to repeatedtly club characters, setting, plot ecetra to divert into another story path. Admittedly some of the best fics I've seen have done so, but you have to ask why they used that series when there's more appropriate ones available for their story or just went to plain Original Fiction seems as how they're basically using OCs with the name tags from the series they claim to be writing about.
