I think some useful filters might be-- Game System Number of players needed (for GMs). Paid or Free Looking for Players / Looking for GMs. Date or Day of the Week One shot or Campaign. Novice or Experienced Player or GM I think at a bare minimum, it should show the Title of the Post in the left column and RPG Game System in a separate column. Alternatively, leave as is but include a built-in drop down Search function (similar to LFG Tool), whereby results appear as they do now but one can search if they wish based on different attributes. In this case, a "show all relevant posts since x date" would be handy to avoid old/non-current posts. Presently there is a Search function based on keywords. Another "rule" that can be implemented is where if a GM advertises for a particular game, they cannot bump that game up the list until after X number of days. On certain play-by-post rpg sites, it used to be that some people would reply multiple times a day causing their advert to repeatedly hit the top of the list, thereby obscuring newer advertisements that got buried -- so site owners implemented a no bumping for 7 days rule. (This does not apply if a legitimate prospective player posts a reply to the advert, in which case the GM can reply).
