I have comments enabled on my site and I require users to enter at least 30 characters to publish their comments (Just to get some value because they usualy just submitted "I like it") But some users now use simple technique to overcome this and enter e.g.:

"I like it. asdsdf dfdsfsdf tt erretrt re"

Gördüğünüz gibi metnin kalanı PHP bu yorumlar filtrelemek için nonsense . Is there a way (algorithm) nasıl?
