The only resistant chain I know of is Grin, because users cannot control, how their data pushes will be represented on-chain, so they will be shuffled in the process, which will make them useless.
The reordering of tx outputs and signatures is one reason for spam resistance (item 3. in [1]), but not the main one. Which is the fact that there's very little room for spam to begin with (items 1.,2.,4.)
