It doesn't matter if your posts are long or short. If you post non-sense content, which as it seems you do, then your posts will get deleted. And yes, non-sense is related with bad grammar. I hardly understand what you're trying to say, and once I do, it is clear that you're spamming for your signature campaign.
Quality is what matters, not quantity.
This is stranger than it seems actually. By the recent screens than OP posted we both reach the same conclusion : The phrases doesn't make much sense and trying to extract some kind of message out of them is really hard. Even if you do reach a conclusion you're left with this feeling that perhaps that wasn't what the OP meant.
What I found very odd, however, is if you look to past posts of the same user the English is totally different. See this one that got him 1 Merit:
When I looked at Bitcoin behaviors from the beginning, it seems that Bitcoin is entering its maturity stage from childhood. You can see that from 2016 to 2018, Bitcoin was very exciting, but after 2018, the excitement decreased and became more logical.
In the general chart, it is characteristic that he has been able to keep above ten thousand dollars for about ten weeks now, and this is the longest time he has been standing in this channel and he has had a sharp drop in the past year because of the corona virus and he came back very soon.
It seems that Bitcoin has become a wise spirit. In the last few days, even a few negative news could not hurt it much, and you can see that it is rising. Last time, Bitcoin fell from 12 thousand to 10 thousand, but it came back to 11 thousand and poured again.
But it did not go down to 10,200 more, and it went up again to 10,900 and fell again, but it did not go down to more than 10,400.
Well, you can see that the floor is tightening step by step, and I think this behavior is very good.
And this stability is very good for bitcoin. I think bitcoin is worth more than ten thousand brushes instead of emotional growth and going to much higher channels, because emotional growth will certainly face a bigger correction.
Another good example (also earned Merit for the post) is the following one regarding TA :

Even this
post from 1st of February (2021) shows a rather good level of English. Then, starting today, it went on to create random replies with poorly written English in some parts of the forum.
I don't want to make false accusations, but I think that the account may have been compromised today and whoever is using it is not the same user that started it. Does anybody else feel the same?
We've been discussing him and his alts every so many months, but for some reason no-one bans these accounts. 
This person cannot be trusted in any way.
