We should respect the theymos decision to keep the forum ad-clean and rely only on the signature campaigns. This is, unlike most sites and forums where you will be seeing ads left, right, front, back, and central. If he couldn't allow profitable ads for a reason, how are you sure he would allow for unprofitable ones?

Besides, most of the examples above are not worthy of your claims except for the Bitcoin Core update releases which is always updated on the forum, it mustn't be so large. Others are okay on their various threads. Even the Bitcoin resource websites are not always non-profit as you think as many are embedded with links. If care is not taken, the forum will be indirectly making money for some people.
