I wonder how you choose them? I see that most of them is from last year, started few months ago.

Do you have any strategy when you choose which one to take? Maybe newer once or actively used could bring more effects?

In the past I also cleaned many of them myself and lately I came across one of many spammy old threads and thought to report and clean it but it is still like fighting the windmills so I leaved it.

I really appreciate what you do because I know how much time it costs, even if you get into practice, it takes a few hours for the work you did. Well done mate.
