[TYPO3-doc] Spam filter prevents editing article

without being an expert on this I think it is not possible to do that 
with regexp technology. You would have to check if any a-tag is 
correctly nested within pre-tags. Regexp can define Chomsky type 3 
languages ("regular languages"), but perfoming that nesting test would 
require a syntax check for a Chomsky type 2 language ("context free 
language"). Basically you cannot fully parse an HTML type nested 
language with regular expressions.

So let's wait patiently for Single Sign On to come.

Cheers,
Jörg.
