That's true, but someone who has a little respect for his profile won't be replying in one; at least that's how I see it. Not all megathreads are awful, such as tournament ones for Euro 2024, the Champions League, etc. However, there are many threads similar to the one I quoted earlier, and people keep posting again and again. It's intriguing. In my opinion, the worst of all is created by some selected campaigns that have massive post quotas; some of them were paused recently, though.
