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.
That's good additional info to add but unfortunately with all the long list of campaigns, not all signature campaign have explained their side why they stopped or ended their campaign. Even some have just stopped and walkaway, like some those mixers who were here before theymos had restricted them, many speculated what happened but its unclear.
