Somewhat. If you open port 22 up on an ip, you're going to get hit by bots scanning the Internet, trying to find an open server to ssh into. If you open port 80 or 443, you're going to get bots looking for /wp-admin.php just as soon as the domain name for it hits certificate transparency logs. The Internet's not a friendly place to be. It once was, but the default now is that someone is going to try and abuse anything you put up. Makes it hard to want to set up a new platform outside of the big centralized ones.
