	Don't waste your time.

	This approach is superficial.  It doesn't actually prevent access to the
	target sites, and is likely to be a nuisance for intending users of 
	legitimate services (web sites or others) which fall in the "shadow" of
	the intervention you suggest.

	Besides, if you take this approach, you will have to commit resources to
	chasing a moving target.

	Best regards,
