You could stop coding client-sided abusive mods...
No. But it can be pretty noticable if someone decides to abuse a mod you created. As Cuddle's said, maybe you can code a helpful add-on that does not put the duplicatons in the folders. I was just saying.
What the forget is wrong with you?
You're clearly blaming the creator of a helpful add-on for the abusive stufftiness of other players, as if the purpose of such user's add-ons were to be abused in the first place.
These are bugs that every add-on will have, it is extremely easy to loop through most complex add-ons and do something at a constant rate that lags the server.
The add-on in question is one of the most helpful add-ons ever released for Blockland, if not THE most helpful.
The duplorcator has a save/load command that seems to use the save GUI for a short time, and you're bashing the creator (whom you think is MARBLE MAN), for the abusiveness of other players.
