I know Pi day is coming but it will take another 11 months, at least.
Although the ads are served by adzerk they seem to be off by a month or so. I saw ads earlier that were for events that were in the past. At that moment I assumed a one-off glitch but this one is too obvious to be considered an incident.
Can someone check with the advertisers if they intended to show and are paying for ads that are no longer relevant?
