Since FC2Web is going down, I recommend going through sites that have sozai you use that are on FC2Web and downloading all images and saving the archived url of the website for crediting of course. Also, FC2 and FC2Web are different. Most sites will be safe.

I don't know anything about FC2 counters unfortunately as I have never used them, but anything hosted on FC2Web will go down. If it's not hosted on FC2Web, it will be fine.
There's also an excellent, inexpensive utility for iOS and macOS. It's like $5 bucks, but worthwhile if you need to save a lot of websites offline. https://apps.apple.com/us/app/sitesucker/id442168834?mt=12
Will it affect FC2 counters? :o

Got it!
Turns out my sister's childhood blog was on there, so thanks for the heads up!
