Please make sure you CamelCase your hashtags. That means, capitalizing the first letter of every word, so the hashtag can be read as separate words by a screenreader and felt as individual words via refreshable braille. If a hashtag is all in one case, it will be rendered to the blind individual as a single word.
Here are some examples of camel case:
