i also run my own one via https://relay.tools which is operated by my friend nostr:nprofile1qy88wumn8ghj7mn0wvhxcmmv9uq3zamnwvaz7tmwdaehgu3wwa5kuef0qyt8wumn8ghj7cn9wehjumn0wd68yvfwvdhk6tcprfmhxue69uhkummnw3ezuargv4ekzmt9vdshgtnfduhszynhwden5te0dehhxarjxgcjucm0d5hszxmhwden5te0w35x2en0wfjhxapwdehhxarjxyhxxmmd9uqzqlxr9zsgmke2lhuln0nhhml5eq6gnluhjuscyltz3f2z7v4zglqws5pak6 not expensive to do and a great way to support a dev/business who is advancing the infrastructure of nostr, and you can configure it to require auth or, like i and others do, whitelist people who i often interact with, some of them their clients automatically try to post to it because it's on my relay list
i think there will soon be an automatic capability to allow everyone you follow to be whitelisted automatically, this is great for decentralizing the distribution of events
