if a user's ignore count (number of times they've been ignored by, say, Full Member+) were displayed, it could be easier to identify spammers, or easier for people to ignore spammers without reading their posts, or there could be an option to ignore anybody who has been ignored by 100+ Hero/Legendary+ members.

although ultimately, this is a business, and i dont expect anything will be done.  most airdrops that new members are going after are worthless, so maybe after people waste enough of their time they'll get bored, and most of the worthwhile airdrops will require more than a forum account.  there are still places on this forum that aren't overrun by farmed accounts.
