unidentified attempts are just standard internet, bots are always poking every port on every IP 24/7 for last 25 years never stopping.
yea good luck with the ghost, otherwise there is always wordpress lol. If you’re wanting reader/viewer interaction there are only a few other than maybe just running a forum and posting .
scans for open ports ran continuously since the 1990s, it was never a big deal. Also they only run on lower ports (not that it matters)
what are you talking about killing your internet performance? You can have hundreds of thousands of scans per day (which isn’t gonna happen, you won’t even get 100) and it still won’t bog down jank cable internet from early 2000s
