Is discussing the prize pool or sponsors now taboo? Why were the messages deleted? Or are all inconvenient questions simply erased here, disregarding the forum rules?

Keep in mind, it's your tournament. May it be successful.
But you shouldn't abuse your power on the forum. I ask that you restore at least my message, as it did not violate the forum rules.

It's just that this topic isn't the right place for these discussions – it will be difficult to find the necessary posts about the tournament later. We need to create a new topic or write in the League section, because we talked about this a lot there – why was there silence?

Why isn't it the right place? Isn't this the place to discuss this tournament?
And as for why there was silence on the League section, I'll answer – we tried to resolve the issue privately. And now the "sponsor" is being announced here. And again with a large fund. So, I want to understand about the current tournament and its prize pool.

I wasn't suggesting that we discuss the League situation here. Moreover, I agree with you that this should be discussed elsewhere.
