Until a couple of weeks ago, The Mix was blocked in almost every country accept the UK. The reason we originally had to do this was because the amount of spam we were getting from different countries simply wasn't manageable, and since we are a UK based service it made sense for us to simply block other countries from accessing our site.
However, recently we unblocked The Mix from other countries. This is because Google doesn't like advertising places that aren't accessible worldwide, so in order for us to show up in their searches, we need to let those countries in.
The downside with this is that we've noticed a considerable increase in spam posts and accounts popping up. We realise this isn't ideal, but we are trying to keep on top of it and find some long term solutions if it persists. You guys are fantastic at reporting this stuff for us and it really does help us out, so please keep doing that.
Any questions, just drop us a PM.
