Can you please add closing reason? like scam or non operational etc. It can help give insights about why they stopped Bitcointalk promotions either it was due to huge success or rug pull or other reasons.
A few of them were because the authority seized the business. Chipmixer and Sinbad are the examples. I can not remember any that have long lasting signature campaign ever thought to scam their clients or promoters. At some points most of these businesses thought it's time to give a break to bitcointalk because they were able to create enough memory that it is going to last as long as they are active in the industry. Good example is Best_Change.
