in the other hand, its very unfair to be canceled for off-topic or poor post, because if i want to post in off topic or i have to post only 2-3 words in my post, what to do? it would be more justly if you just dont count posts likes these and didnot pay for this post.
No, what's unfair is people lazily shitposting all over the forum and expecting to get paid for it. I wouldn't have a problem with people posting in off topic but when their posts are all just 'pepsi' 'cat' 'i like cheese' 'Total time logged in: 5 days, 13 hours and 34 minutes' etc everyday they're not doing that for fun and the only reason people post in those shit threads is to either farm activity and/or get paid for the minimum amount of effort they can be bothered to do.
How do low quality posts look like, because I have never made a one or two word sentence in my posts, minimum I make is five
They look like yours. Pretty much every single one of your posts is pure half-assed spam. Just because you add a few extra words to your posts doesn't make them any more constructive. Saying 'I really really like Pepsi' isn't any better than just saying 'Pepsi'.
