I have some posts that are deleted from the forum by moderator. It is a sad thing when your post is deleted by the mods. But now I know why my posts are deleted, either it is off topic or spamming or both. And if you do it in several times, your account can be deleted by admin or mods because you break the rules and they have the right to do it. It is for the better of this forum too, because if there are too many spam posts or bad posts, it will decrease the quality of the forum too, so it is their job to keep the forum to have a good name.
Instead of complaining, I suggest you learn English because it is the language used in this forum outside the local board ( and you can use English in real life too for your activity or work or business, so it is a win-win solution), then try to learn about cryptocurrency.
