I find it interesting that the risk curve around how permissive a host is. If they're not permissive, they're possibly going to take your server down at the slightest external pressure. If they're too permissive, they're probably hopelessly embattled and might themselves go bust. But what's the sweet spot? For me, I mostly buy nearlyfreespeech.net's shtick (though less so nowadays) and have used them for about 20 years now, but am always keeping an eye out for other tolerant/stable hosts.
