Webmasters may feel that this is the safest technique to avoid losing potential visitors. However, such repetition may be considered by the Search Engine to be Spam! After all, higher the number of words, higher the combinations.
The best way to get around this problem is to list keywords in lower case only. Most surfers always search in lower case. There are very few cases where surfers use capitals even if the word is a proper name. Of course, you may run a very small risk of losing a few visitors who use upper case, but this risk is minimal. Besides, you do not want to be banned for Spam.
