First off, we don't require people to give input when giving a +1/-1. Your attitude towards those who do is a risky reflection of how you would handle conflicts as an admin.
You have a few valid reports under your belt, which is already an improvement compared to many other applicants, but you make it sound as if there is a constant flow of problems. If that were the case, why haven't you reported more of these incidents?
I also want to bring to attention that you were fervently advocating for a complete ban of anything pornographic, which, let's be honest, has been a part of TF2 for as long as most people can remember. Your attitude and responses in that thread were less than impressive, and you tended to attack people rather than their arguments, which is NOT a good sign for any admin candidate.
As others have already stated, you also have less than the required amount of playtime on our servers. It goes without saying that AFK hours do not count, regardless of whether you think it should due to being a trade server, which should have people in it for TRADING rather than being AFK like in the idle server.
Overall, this app was already denied but I will re-state that, even if you did have the minimum playtime required, your attitude towards other members and lack of reports would still have made it a -1 from me.
