That would be great … thank you 
It doesn’t need to be a different account. Most people seem to be simply switching to a different character (or perhaps sometimes they have two people doing recruitment posts … but pretty sure in the majority of cases it’s the former).
However, as mentioned earlier, and as @aerythlea kindly mentioned, it does seem a bit too strict to have the general forum rules in that regard apply to the realm posts (which, by their nature, are much less often frequented/replied to).
I don’t know if they’ll be able to make the realm forums an exception though … it might just be one of those things that, as it’s a rule applied to the parent forums, any child forums inherit the same rules.
In the meantime, it appears the only way to keep your realm forum post active, is to ensure you reply to it yourself once every 30 days (personally, I try to ensure it’s less than that, just to make sure!) albeit with a different character, alternating. See my forum post as an example … Willoh is my alt (on the same account):
By the way … I found an example of someone who seems to have managed to not need to switch characters … but it may well be due to the fact that the thread was ported over from the old forums? Delete (recruitment closed for now) - #10 by Tsumiki-lightbringer
*Edit … I’ve found another … it was created after the forums were moved over, one person created it, and then another, on the same character both times, has replied, and then replied again, with no other replies in between. So either they’ve done that “fix” or there’s just something odd going on. [H] Endurance is recruiting!
