On the topic of this flash, and an explanation of your score. I do understand that this was made very quickly, and while you were angry, but it is also fairly low quality, and there is no sound, which (agreeing with another poster) was a bit distracting from the flash overall. As quickly as you scrolled through the forum post it was hard to really get the gist other than that you were disqualified this made it hard to empathize with the main character, especially given their extreme reaction. Overall I can give this a 2/5 and a 3/10.
That being said, and on the topic of Collab rules. Not being familiar with these rules I went ahead and looked them up. The rules are pretty straightforward and understandable. They don't say that you can't start a collab, just that you can't use the Newgrounds BBS to start one. Reason being they want collabs started on site to be started by experienced and quality flash artists who are up to the task. I know there is a ton of nasty spam on newgrounds, i don't know how much of those collabs come through the BBS. I would like to think none of the KK, TT, or whatever random other spam groups work makes it. Spend a bit more time polishing your flash, organize a collab outside of the newgrounds BBS. If you think you can do it, do it, or at least try. It beats the crap out of whining about it.
