I believe this is, sadly, becoming a norm worldwide.
I actually try to do some damage control now, as one of my e-mails has been used to subscribe to almost every possible brand newsletter there is. I'm sure some spamming bot has been used. But this also hints at how "moral" contemporary businesses are in trying to get people's attention.
At first, I thought I will just write to the companies that the junk mail arrived from but then I changed my mind because:
1. That would be too much of a hassle.
2. It might be just what they want - my attention.
It's neither a precious or a business mail though, so I'll just delete the account after I "evacuate" everything valuable.
