This is just a measure to communicate to our users how to behave. You don't need to write anything agreeing or disagreeing here (unless you want to). We are not asking for this, just passing on information.
Your last post agreeing to the rules was deleted by Blockio probably because they didn't understand it. Remember, just because I and a few others here understand Portuguese, it doesn't mean everyone does. Try to just use English for now.
But thanks for the feedback!

Ah ok
I'll use Google Translate more to talk

You can use a language other than English in private messages (PM), but we recommend this only when both the sender and recipient speak the same language.

Cause the forums aren't as active as they used to be I was wondering if replying to threads older than three weeks is still considered necroposting if the thread is still on the first or second page?

The rule of thumb is the further back, the more substantive any necropost should be; that said, the front page should always be fair game.

Nice to know the rules of necroposting. Thanks!

By the way, I just wanted to take a moment to sincerely thank you for your hard work and dedication as moderators. Your efforts in keeping the forum organized, welcoming, and informative do not go unnoticed. Your patience, fairness, and commitment to maintaining a positive environment (although the forum feels abandoned) make a huge difference to everyone here. It’s clear that you truly care about the community, and I am all grateful for your time and effort. Thanks again for everything you do!
