My blog (@coxy) is hosted on a very small server package from the hosting company. It costs me about £10/month and does the job just fine.
Until I installed the #ActivityPub plug-in on #WordPress and now every interaction I get from #Mastodon to my WordPress blog takes the site offline.
Me: "Go check out my new blog post... in about 30 mins from now when the site will be back up again."
