Don't feed the troll. The OP is certainly a troll and possibly an alt of another account, which very likely is denied from all signature campaigns because he's a shitposter. Thus, what's more logical and reasonable thing to do, than to create a new account and bash at everyone else who's successfully enrolled in a campaign.
It's more of a yes than a no. If you look at the recent influx and aggression of some trolls, then maybe he, or they, can't calm down.
So, from what generation are you coming and can you remember your old username?
If he had an account before and he doesn't talk about it because his "history isn't entirely clean," then I think he'll "try to forget" the nickname. Although even old accounts on the forum are revived after losses, if desired, here, as you can see, is another story.
Reddit is not good either...
OP "broke into" the forum with his idea, but after he was disappointed by Reddit, thinking that he would find like-minded people here, he realized that his ideas did not impress anyone here either, and began the usual criticism of a weakling.
OP, you should not blame others for the inattention; rather, look in your direction. Perhaps you have flaws, and therefore it makes sense to improve not society, but yourself.
