Isn't it much simpler to have frontends manually "censor" this account? People who are interested could follow it and frontends can easily remove it from the trending page.

It's a general solution to a general problem as opposed to manually modifying the front ends for a one time solution to a specific issue. And from an implementation point of view, it's also less work, IMO.

oh yes, censor. what an absurd idea!

You can still see everything on the blockchain, it won't be censored there.
