I'm assuming it's only there to prevent spam, but most guilds check out each member before approving them, letting them into the guild.
So it'd be pretty unlikely for someone the guild/guild leaders trust, to just go on a spamming spree, unless ofc, they get mad about something,
and in that case, the leader can just kick the person / delete the posts.
Yes from me, Jos!

P.S. - Let me know if I completely missed the point of this suggestion. I think I understood what you were suggesting.
