"Please reply "STOP" to stop receiving these messages" - naming organisations who spam academic email addresses

As someone with an ac.uk email address I am regularly added to mailing lists without my permission. The first time I'm aware of it is when I get some spam and it ends with something like -

"Please reply "STOP" to stop receiving these messages."

or

"You have received this email because you have subscribed to The Bridge to Success LLC as [my email address]. If you no longer wish to receive emails please unsubscribe."

Since I've not signed up to receive these messages in the first place I suppose, by definition, I'm unable to unsubscribe ;)

I've had two of these today so am naming the organisations who spammed me here.

• The Bridge to Success LLC (web address includes thebridgesuccess)
• EdifyOnline

I've no objection to people emailing me to tell me about their organisation and invite me to join their mailing list but adding me and requiring me to take action to remove myself is guaranteed to get me irritated enough to start a new blog post about it. 

Naturally I searched on Twitter to see what others had to say about either of these organisations.

I keep getting solicitations from EdifyOnline and it's all sorts of red flags:
1. Looks like another "disrupt education" plan- uberizing higher ed, and more efficient exploitation of adjunct labor
2. An ed tech company w/ no twitter account pic.twitter.com/nGR107HaYJ

Twoogling also indicate that MIT and EdifyOnline are collaborating so it seems to be a legitimate organisation, but I still hate being spammed.
