is there some altcoin able to prevent spam?

Hi all, I'm looking for an altcoin able to prevent spam using something strongest than fee.
I will use,improperly, the term bitcoin, to call a generic currency able to prevent the spam in a realistic way.
I consider every transaction which scope is different from coin transfer as spam.
I think services like omnilayer, opentimestamp, coloredcoins et simila are blockchain spammer as the value to use the blockchain for those kind of transactions can be greater than the value to use the blockchain to transfer bitcoin. So they have reasons to pay bigger fee preventing bitcoin transactions to be performed succesfully.

I think blocks should be as little as possible, and blockchain should be used only to transfer bitcoins.

Smart contracts like lightning network are ok because they are used to facilitate bitcoin trasfert

I'm sorry for the noob question, and for my english,
if you think I'm stupid, or the coin I'm looking for is unuseful, please keep it for yourself
