A one day ban is essentially a slap on the wrist and is essentially a stern warning not to break this rule. The majority of bans are at least 3 days (with many much longer). If you ask nicely it is possibly that BadBear and/or theymos might lift your ban early (if your ban has not already expired).
I would say however that I do not agree with this rule, especially when there is no paid signature involved. Posting multiple times does have clear benefits as it makes it very clear that you are making multiple points in relation to a particular topic. Making one post and then a subsequent post immediately after helps empanthesize the second post and would be beneficial to someone making a series of points concluded by a strong/important point.
On the other hand, someone with a paid signature has a clear incentive to make multiple posts, often times responding to posts that was not directed towards them and that has nothing to do with them in order to pad their post count.
I would strongly encourage the moderation team to increase the consecutive post limit to above "one" especially when there is not a clear case of paid post padding and to be very liberal when enforcing this rule, especially with those without a paid signature.
