Oh. Thx you
I agree. No NSFW content
We can speek free all about anything but no NSFW
It's good

It's not a bad idea to remove junk and spam messages. But I would like to know about how post quality is determined and I would be glad to hear about all the factors that makes our post spam.

I too want to know the same. Many user are saying about many factors that makes our post spam. Although my messages weren't deleted every bit i am rather afraid of sick policy. I would be happy if you provide the link or say me about full policy.

where I can learn the rules of this forum?

EDIT:  Wait, does +1 count as a zero-value post?

The policy to not remove anything worked when the forum was small. Now that we have thousands of posts a day, we can't afford 50% of them being junk. The moderators are now instructed to be less tolerant of low-value posts.

Some guidelines:

1. Free speech - you can say anything as long as it is relevant and presented in a calm and polite manner. Swearing, SHOUTING etc. make your post more likely to be removed.
2. No zero value posts or threads, like "SELL SELL SELL"
3. No pointless or uninteresting threads.
4. No referral code spam
5. No NSFW content

How many minutes, or messages I need to send or spend here in order to increasy my level from newbie to member? is there a list or reference for this at some place here?

are post allowed here like for marketing but in a descriptive manner not really sounds like selling or in short are we allowed to post company brand here.
