I think this is a bad thing for a number of reasons.
- If the announcer doesn't have enough belief in his product to monitor his replies, then he is unlikely to support the product, and we should ignore it.
Similarly if the announcer doesn't have enough interest in the forum to become an active member, why should we consider his product.
If the thread doesn't get any active replies or comments, then it is unlikely to be of benefit to the members here, so it should be allowed to drop, and leave space for better quality products.
The forum has paid advertising slots, please use those instead of trying to inflict marginal products on the members here without paying for the advertising.
