The question What is the best program to uncompress .tar.gz files on Windows Server 2008? has an accepted and multiple up-voted answers more than five years old.
Then suddenly it receives three new answers within a couple of hours. All of those answers are somewhat similar sounding (mentioning the same two programs already suggested in five year old answers), and were posted by users who posted nothing before today.
Is this just a bunch of newbies who don't understand this site, or is something else going on? What's the best way to guide these people? Should such answers be flagged?
