Have received 100's of emails from purported Dropbox users asking to be removed from a mailing list. Each has 22 CCs. Everytime someone replies, more spam is generated. Major issue. Reported to Dropbox support, awaiting response. Problem is ongoing - got another bunch while trying to report the problem. Dropbox impenetrable "support" system is part of the problem. I'd pay to speak with a human but can't find a way.
Any ideas? Please help.
