So where's the content change. I don't see any.

The bot changes some references with the name parameter set, but not all of them. See this dif for an example. The bot sets

|arkivurl=https://archive.is/2012.07.23-082505/http://www.chartstats.com/artistinfo.php?id=480

on two of the references with the name "UK's Albums/Singles positions to Ashanti". However, there are two more references with:

|arkivurl=http://archive.is/Qutx

I think I see, but I'll be honest why use reference tags with the same name? That's just silly. If you want to use the same use a contentless self closing ref tag.

I totally agree. Hopefully most users use that method today. But there are probably a lot of references with the same name in old articles (and some new ones as well), so it will happen again. The problem is not huge, but I thought you wanted to know about it.

Thanks. Since it's not a huge issue, I hope you won't mind if I decline this issue.
