I don't remember exactly when (definitely 10-ish years ago) but I used to have a Japanese IDN that was like "hard disk recovery" and another "virus scan" or something that would make about $1K / month in AdSense. The good 'ol days
.
I was going to make a customized "parking" platform for my IDNs a couple months ago but just too damn busy. I'd really like to see if there's any juice to get them performing again.
