Personally I have seen plenty of posts from Gil deserving of strikes, and I'm glad to see him leave if these are the posts he continually, and consistantly makes.
You say you're being singled out. Perhaps this is because you ARE the worst offender? I have managed not to butt heads with the moderators, as have the majority of other members on these boards, and I am not always positive about peoples' work. You seem to go out of your way to post something extremely negative, and not at all constructive every time you see something that you percieve to be below some imaginary standard you have invented that is required to be an active member of Pixelation.
I have seen Helm on occasion say to members that they would benefit to learn the basics before trying to experiment further with pixel art, but he has always appeared friendly and genuinely helpful when doing so. The problem is not what you are saying, as what you say in AdamA's examples could very well be valid, and is very similar to the advice Helm has given on occasion. The difference is your posts are demoralising. Some of these people are 11, 12, 13 years old, and they don't deserve to be put down like that for trying something new.
I have a younger brother who is only 10 and whilst he isn't particularly talented at drawing for his age, he is very enthuesiastic about learning to get better, and deserves the chance to improve without negativity being thrown at him. It is a right that should be extended to everyone on these boards. Not everyone is trying to make a living off of Pixel Art. For some it is just a hobby, and that has to be respected as well. Not everybody can be the next Da Vinci. They see something that inspires them, and so they want to do it too, and you damn them for it.
The fact is I've been around on Pixelation for a long time as well, I'm not sure about our exact join dates, but possibly as long or longer than you, and the first thoughts that come to mind when I think of you and your posts are of someone who thinks he's somehow better than the newer members here.
If Gil was ever a limb, he is a festering one now.
(It isn't nice to hear others being so negative about you is it? Bare that in mind.)
