people should bare in mind that filters are not a good safeguard to be dependent on, as all filters some way or another can be breached which make every device a potential problem regardless of its filter status....the best filter is the one that u create within urself meaning that u are properly aware of the risks and u are very well educated about why u shouldn't want an unfiltered device, this changes the dependency to something more realistic...and only then can u take advantage of a filter which will aid you in protecting what u instilled in yourself. of course never trust yourself, because the facts are that u simply cant always trust yourself, but a filter is much more powerful when it is used with a person who is himself "filtered", because both him and the filter are going in the same direction.
just some wisdom to ponder....
