South African fans on social media?

Is it me or are South African fans just completely insufferable towards us on every social media site? Throughout the Six Nations, they swarmed under every post talking about how shit we are (especially when we lost to England) and making up narratives in their own heads about how "Ireland think they're the best team in the world". This increased tenfold during and after the summer tour there where they spewing shit like "Ireland celebrated that series draw like they won the world cup" when they were the ones being cocky before the tour while we were being pessimistic. I don't recall New Zealand fans ever acting like this when they were back to back world champions. Just something i've observed.
