I support the club actions in this case - the 'tweets' were in a public sphere to a well known fan with a large following. Perhaps more weight with the club @evertonfc tagged prompted them to act. I don't think Ric Wee made much of it, just that the PR team at Everton follow Ric Wee on twitter, and would have seen the abuse directed to him. I think if private
That being said, I think people should grow a pair and stop being so precious. We had a case here in Australia where a 100kg 1.94m footballer was called an 'ape' by a 13 year old supporter. He said she really hurt her feelings and dragged her through the national media cycle for a week or so, prompting an apology by the club, and the fan herself. Best response I've seen to racism is Dani Alves and the banana - class.
