It's been said before and I'll say it again. Just because it's verifiable doesn't mean it deserves an entry.
Anyone visiting my website would be able to write a very verifiable article about it, but the fact remains that it receives very little visitors and simply doesn't warrant an entry in an encyclopedia.
Now, Alexa may be somewhat biased to a certain group of American users but that doesn't mean it's entirely useless in determining traffic, especially in combination with Google hits and mentions in press and webzines and activity on a webcomics forum. If most or all of those criteria are lacking, it's just another website one of the approximately 4,000,000,000 on the net.
We can't have an article on all of them, just because they are verifiable.
And even if something warrants inclusion, it doesn't mean a 2 sentence stub on a character needs its own article. Merge it into a parent article and provide it with loads more context.
