For the time being, I've come to find out that posting smaller details about our guild, updates and things of that nature, is what they're looking for. They're trying to prevent 12 pages of pure "bump".
Do I agree with this rule? No, of course not. Saying "bump" is much easier than having to think of something to say. But I do agree with what Blizzard is trying to do (prevent spam). I just think they went about it the wrong way.
Thing is about this is it is pretty much pointless to post anything past the first post as people expect that initial post to be updated (which it is going to be if the people are caring enough to bump it, they're caring enough to keep it accurate). No one reads the babble below it. Which yes, you could say is because they don't expect anything below it... but honestly unless the person is extremely bored, all they are initially caring about with finding a guild is:
Finding raid times that fit their needs (always in the first post)
Finding progression that fits where they want (always in first post)
Finding a guild that is actively recruiting their class and spec (always in first post)
Finding out about loot distribution, whether it's a form of DKP or loot council (always in first post)
Past that, I guess you could learn what kind of people they are, but most guilds have a guild charter on their main page explaining that, which is accessible via a link in the initial post... people aren't going to search through 2-3 pages of one single guilds recruitment discussion, people don't often look past page 5 or so on here.
These new forums are roughly a month old now (not fully) it looks like there are posts from Nov 5th on them as the earliest, but, I know myself and many others just became aware of them with the closing of the other forums (or inability to post on them) these have quickly gotten more attention, we have 35 closing in on 36 pages of threads on here in that time... the majority seem to have happened the week of the 16th when the old forums became outdated and unable to be kept current for posts as. Back on page 32 there's posts from the 16th of november, aka last tuesday.
There's 50 threads PER PAGE so 32 pages back... that's roughly 1600 threads posted in a week that have pushed those to the back pages... ok, a week and 1600 threads ahead of your recruitment thread that's a week old that can't be bumped... that's on average 228 threads a day being posted each day of the week, so in one day your post is back on page 4 and half way down it... this means your post is relevant and having a chance of being read for at maximum 2 days before it starts getting overlooked for being too far back on the pages... and honestly these forums ARE NOT as active yet as the old ones as I'm sure not everyone has seen them yet and this is not prime time recruitment between expansions as the wave of players is not here yet...
Not to mention if the post the person was bumping got deleted (like mine did) and I'm sure MANY others... that would put the forums back even further. They aren't thinking with this rule on a recruitment forum.
Essentially to put it simple for blizzard's eyes, it'd be like any TV station saying to Blizzard you can only advertise once a week on our station... once a week! So pick that one time and then forget any additional advertising for you because we don't want you spamming our viewers with information about your product... it's the same concept here with guilds not being able to advertise.
You see a guilds post once you might not look at it real close, perhaps it's a close fit but you're still debating on guilds and then you lose that guilds post because of it getting buried or you just don't know if they filled the slot yet as they can't keep it around in a place you can see it, perhaps you're just TOYING with the idea of leaving your guild... hundreds of reasons can apply to this. Point is the more you see something, the more likely you might be to give some more thought to purchasing or trying it.
