Gotta get yer fingers off the "Post" trigger, or Soya's gonna come stompin' in wi' the jackboots on!

As with so many things in life, sometimes the 90-second rule catches you even when it's not true. I mostly see this right after I log in (usually to respond to a PM). Sometimes it's legit, tho. If you know you haven't posted within 90 seconds (better be sure, Comodo knows the truth...), then you can post in these boards, with the exact date/time, time of last post, etc.
