Urwumpe you cannot jump to conclusions like that, for all you know he is attempting to translate into another language.
I can.... easily. If you read "Rag Tag Fleet" when you download something and just fly it (so you have read the name about 6 times at least), you won't write the name wrong, since you can read how it is spelled pretty often.
Especially if you are translating in another language.
Also, your conclusionof him translating from another language into English is the poor one. If you read his post, you will find out that he writes a phonetic English: He knows how to speak the words, he is just incapable to properly write them. He could be dyslexic, but then, people who really are dyslexic and know it, usually don't write names wrong that they have just read, since they can just type them letter by letter. Even a strong true dyslexic will rather do the other everyday words wrong that you rarely notice being typed.
This one simply looks like a chatroom dyslexic: People who are so busy typing their chatspeech lines as fast as possible in what ever medium available, that spelling, grammar and error correction become unimportant.
