Oh believe me I know it does that. I have to constantly delete double or triple posts because of it. I don't know exactly what it is, and haven't really troubleshot it, because I'm planning to move the forum over to a brand new virtual machine I build about a year ago with the latest version of CentOS. I spent a lot of time on it. It has automatic cert renewal with LetsEncrypt and two replicating instances of MariaDB so I can back it up constantly without any performance hit. The reason why i didn't immediately move the forum over is because it will require upgrading the forum. With all of my customization, this is going to be a huge job. Just expect to see a new forum with a dark color theme soon.
BTW if you took a look at the IP's you would see it is indeed in a data center, Digital Realty in Los Angeles to be exact.
