Reputation and flag are closely linked to Stech's blockchain, not the front end. So, in this case, I comment on Steem.

About regulations, I doubt there's any chance of that happening, and I'll say why.
Let's imagine that governments force Steemit Inc to take this post on the air for example. What could they do? Within STEEMIT, they could create a redirect that, if someone tries to access this post it will not appear, or it will be redirected to an error page, for example.
BUT ...
As we are talking about a front end, we have other options such as Busy, Steempeak and Steeve, which are mirrors of the STEEM blockchain and not STEEMIT. This means that in these other places, my posting will be visible unless governments try to file a lawsuit against all of them, and even if they do, they would have to do with all the applications that use STEEM to come in the future.
Even if Steemit Inc wanted to, it would not be able to change the block in which this post is, and consequently they would not be able to make this post censored completely.

So, in conclusion... You can only censored something in STEEM blockchain if, and only if, you can change the block of that post, which, in a such way, it's impossible.

Cheers!
