Spamming comments?
Can you explain to me how is Building followers base by welcoming new commers is a spam?

You were doing the welcoming in a very high frequency. That's why it is spam.

okay, now i get it.. would you please tell me what is the acceptable frequency? because i didn't know that there is frequency rules.
and i still don't understand what is wrong with that..

Don't use the same message again and again. You were using the same one again. If you use the same message twice or thrice within a short time, 20-24 hours, it could be seen as spam.

Also, posting comments without reading the post is also frowned upon. And irrelevant comments are also spam.

Oh wow... now I understand what I did wrong

I am going to remove the downvote
Please let meanpeoplesuck account owner knows that i did
