When I post something on bitcointalk, do I still retain ownership of that, or does bitcointalk retain ownership in it? Are my posts still my property? if so, why did you not notify me when you removed them? These are some important questions admins will need to answer with GDPR upcoming, which will affect the forum even though it is US based.
A forum post is not a physical entity, and there are numerous copies made whenever a member opens a thread. Surfers have the right to delete your post from their computer. I'm sure the forum has a similar right. In fact, isn't there some stuff in the forum registration agreement which says that the adminshave a right to change or delete posts if they want to?
If I buy a book, do I have to get the authors permission to burn it? Isn't this much the same argument?
