*Who* is doing it is irrelevant. The important question is *why*. Ripple questions are getting close votes, but nobody's spoken against Ripple's inclusion [in this discussion](http://meta.bitcoin.stackexchange.com/questions/335/should-this-se-also-cover-questions-about-ripple). (edit: AntonAnsagar has now, and Stephen Gornick posted something that can kinda be [interpreted either way](http://meta.bitcoin.stackexchange.com/a/345/2306).) There are two possible reasons for that:

 1. People voting to close are unaware of the previously linked discussion. I think this is unlikely; you need 500 rep to cast one, and I would imagine that somebody who's been here that long would have visited meta.
 2. People voting to close feel that replying to that post wouldn't convince anybody, and that making close votes on Ripple questions is best approach to winning people over.

What should we do? Nothing, until 1) they make a meta post explaining their position or 2) gain enough support to actually close questions. 

One more thing to remember: this isn't Us vs. Them. We're a community of people, and while we might disagree on some minor points, we're still going to build a kick-ass reference site.
