Zaps, reactions, boosts and follows can all be faked and abused...
Just because something can be abused, does not mean that it will be.

Most polls will not be abused because they are not worth the effort to attack them. There is no value in coming up with a ultra secure polling system that no one will want to use because it's not frictionless.

We desperately need zapless polls. 

 Exactly, people are acting like every poll needs to be securing against a rigged election lol. When realistically most polls on social media are like 'Do you think this apple looks like it's too rotten to eat?' or 'Does my bum looks big in this?'
