Bleach bit and other industrial/military strength erasure systems aren't recommended for Solid State drives for several reasons. First of all, solid state drives don't hold ghost data as easily as other magnetic memory does, and don't require multiple overwrites such applications provide. A single overwrite is more than sufficient to completely erase the data on an on/off digital memory. The iPhone's memory is so fast, it does that with its erase command. Unlike the data tables of a standard hard drive which just resets the memory map, the data is quickly overwritten with zeros. There is no ghost of what was there before that would require a multiple rewrite to be certain there is no remaining remnant of any magnetic hints. Secondly, even the best solid state drives have a limited number of read/write cycles and you really don't want to use them up needlessly doing unnecessary erasures of this type.
Apple has recently removed its "Secure" delete from its menu option for this reason because they don't need to work on SSDs they way users think they will. It is still available for mechanical, magnetic drives from the Terminal, though. I think Apple should have left it with the automatic option for the mechanical drives, testing which kind of drive the user was using.
You can get adblock, but more and more websites won't load with adblock activated because it impacts their revenue streams. I'm seeing about 15% complaining about adblockers.
Drudge and others are putting out "complaint" signs for users with adblock to ask them to whitelist.
