I suggested this in May ( if you used the search facility



).

These are not ripped to download, as the only ones that people rip are bought and paid and this is not allowed here on BHW.
I share these for what they are, a free ( at time of posting ) learning resource.
Personally I don't have any affiliation with Udemy, I just share these courses, which are free when I post them.
If people would prefer me not to share then all it needs is someone to suggest me not to do so.
Obviously as part of the Udemy platform people need to enroll, otherwise how could you access the course ?
As for the mailing list part, yes it is the course builder who gets your email details, not the person sharing the course.
Use a spare / disposable email address for stuff such as this. Then you can always unsubscribe to their emails.
For those of you who have the capacity and time to rip, then upload to MediaFire, run a VT scan for a free course, I applaud you and invite you to do just that.
But as I say, if people don't want these courses sharing, feel free to comment to that effect.
