I don't think that your suggestions are reasonable. The most memorable phrases we use are also linked to our understanding of certain specific concepts, on a quite personal level. Essentially, you would be forced to generalize everything, and could be left only writing banal youtube-style comments rather than anything reflecting your best attempt at getting your thoughts down. At that rate, why bother writing?

I think better protection is simply not to publish much under any alias. If there isn't a large body of text, an alias writing a few thoughts on one or two issues can't really be mined.
