Lol. They won't. A small team to delete repetitive emails has nothing to do with getting hundreds of emails a day from different people in your constituency. Also "weak free speech" is pretty much just a US-centred meme.
People get arrested in Germany for saying bombing little kids is bad, and I think it's the same in different countries. Each one has a few issues the leaders really want to get done, and you're punished for opposing those, but you're allowed to protest the ones they don't really care about.
In every country where I'm aware of it, emailing your MP does not email your MP, but emails a member of their staff who read most emails and delete them, unless they're actually something the MP actually cares about, like a bribe offer or something.
