LPC, not quite a Noob, with "1,391 posts". The thread was posted some 18 hours ago, so probably no granite pizzas (unless due to a later too-far-off-the-commune post). It probably got several Post Reports and appeals for MIRT action, though.
Rather verbose, could have made his/her point with:

* Shifting purchases to a day before or a day after will not matter at all and probably would not be noticeable due to non-boycotters.
