my account has been banned from low content for 15 days. The ban was lifted today.
It is possible to have diverse opinions from that of the moderators (not all mods agree on particular issues and some are more stringent than others), but the key takeaway is that it was a temporary (warning) ban which is lifted now, and you should try and improve your post quality to avoid it in the future.
Apart from that, my articles have been given merit. However, even the merit post was deleted due to low content.
Quality is subjective and users merit what they find worthy of their smerits. This doesn't serve as a benchmark for what posts are quality.
