A platform that can only deposit, but not withdraw

It’s okay to list coins on the ZT platform at will, and you can draw pictures at will! You draw any picture, and I recognize it! You also secretly took down my coins! Off the shelf! I got it too! You still don't withdraw coins! You don't withdraw coins! Forget it! Also put me on the blacklist! ZT is too dark! Mute me! You are out of sight and out of mind! ZT, you are such a fraud platform. Just clear my assets to zero!
