Spam?

So what is spam?is it anything you don't agree with?
Looked up spam and by dictionary definition 90 per cent of posts are spam.
So what do you think?
It this spam?
Is your reply spam?
I just wish someone could clarify this.

Your questions are beyond my understanding

irrelevant or unsolicited messages sent over the internet, typically to a large number of users, for the purposes of advertising, phishing, spreading malware, etc is called spam.

This is spam: <comment deleted by user>

Messages That Are Not Proper, That Are Irritating People Are Called "Chat Spam". So, Really, That Is Just A Word I Came Up Of! E-Mail Spam Means, Infected Links And Files Sent To You. Those E-Mails CAN 99.9% Contain Malwares. I Use SOPHOS.

Yes I know the definition of spam,.yet many posts are doing none of that yet they're still called spam.what is spam by lichess's definition?

Write same thing many times, advertise, etc.

@Dukedog Here Is A Snippet Taken From The Forum Etiquette:

"Spam Means, Posts that are purely promotional are not welcome in the forum. Lichess ask that you keep all advertisements outside of Lichess. This includes asking others to join your team or tournament, or check out your YouTube channel.

✅ Click on the Report-Button in the right corner of the post if you think someone is advertising in the forum. Moderators delete posts/threads that advertise and take appropriate action towards the user

❌ Don’t make threads for: “follow me”, “ join my team”, “join my simul”, “subscribe plz”
❌ Don’t make posts that encourage spam: “How many likes can this post get”
❌ Don’t reply to the thread, giving it more attention"

yes these are the examples of spam

@RiShAbH_InDiA
Yes, I've already read that it just seems to me that spam is a subjective judgement and many posts are called spam who advertise nothing.i once got a spam deletion for posting if you unfollow me I will unfollow you.how is that advertising.it was only a joke.
