this is advertising, right?

Bob · 2022-03-29 20:13:12

The forum rules do state "No Spam. Spam includes messages .... that are .... promotional in nature."

If someone advertises a commercial product I remove the post and usually the member. I have checked out these videos and they are genuinely mathematical teaching aids, offered for free. We have had, for some time, another member regularly posting links to similar material and no one has objected to that. I have, therefore, been happy to allow these links to remain.

Many U tube videos start with a commercial advert. These don't.
