I don't think anonymous voting would be included on Steem, but if I mentioned it in an SMT alone, people wouldn't think that much about it, just push it out to "later". :)

There are pros and cons to it and one of the cons is that (if forced) anonymity takes away the attractive power of stake and the ability to influence the platform past the voting. Influence comes in many forms and like it or not, the having of stake is one factor.

I am interested in how behaviors might change as from as far as I can tell, if one was to compare the difference in behavior between the "known" and "anon" accounts when it comes to bad actors, I would say there is a clear bias toward the anon. Would masking stake make it more prevalent?
