Repeat after me, decentralized exchange blocks users, decentralized exchange blocks addresses and ips, and if you're wondering why I ask you this do it till you finally realize that a truly decentralized exchange won't be able to do such a thing.
This is why the whole Defi is just a buzzword and the whole industry is just a failure, there is nothing truly decentralized, it's just like the FinTechs were supposed to change how we do business with the banks and credit cards and in the end, ended up becoming banks and using the same infrastructure.

Same here, all these Defi exchanges are turning into things just as centralized as the traditional cex.
Not to mention that the shitcoins are now just as centralized as you can get so they might simply block your address from transacting on a whim.
