To the Campaign Manager, may I make a suggestion?
I think you should open up your posting to Games & Rounds, Politics & Society, and local sub forums.
Omitting these forums from your paid campaign is leaving a lot of potential customers in your target market absent from your campaign exposure. And since other campaigns also avoid those forums the threads aren't clogged with the noise of other campaign signature ads. Your add would stand out from posts and posts of nothing, i.e., your posts in those forums will be more impactful.
Last, opening posting up to these forums doesn't cost you any more in campaign rate payments!
Think about it.
If other campaigns don't let users post in those sections, there's probably a reason why- i.e spammy subforums. Many subs just have mindless posters who don't even bother to look at signatures and those areas aren't worth advertising in to most campaigns.
Campaigns are based off of advertising and there has probably been some research or something done that suggests posting in those sections does not help out exposure to the advertised site as much as other sections. Remember, the payment is being given in exchange for site exposure.
Local subs are also not a good idea because many people do not speak English nor read English in those subs and those people will likely not even know what the signature or website even does and how it works. Then there's nonsense subs like politics and society where people aren't really talking about bitcoin at all.
There are already some campaigns requiring posts in games and rounds, and honestly most of those posts are pretty pointless and add almost nothing to the ongoing thread. Meanwhile there are all the other subs and threads that might actually help people out like mining.
