I'm not suggesting you can't ask the question. All I'm doing is pointing out that not getting an answer might not permit you (according the the arbitration ruling) from doing anything much about it. However, I think this is entirely a hypothetical situation, as finding a citation that backs up the scientific community's rejection of astrology as pseudoscience will surely not be much of a task. If nobody steps in, I'll have a look myself tomorrow - I should be in bed by now...
