recently I have had many people posting url's to their games into my game server and now decided to code a world filter system, so its a database table with lots of words in it. What the problem is, is that they keep bypassing it.. like below

I first blocked "universegames.com"

they post u niversegames.com

I then blocked "u niversgames.com"

they posted un iversalgames.com

do you get what I am saying? is there any better way to do this other than blocking them all 1 by 1? they keep adding gaps and symbols inbetween etc..

You don't know how to trim white-space from a string? – 500 - Internal Server Error Feb 18 '16 at 16:26
Like I said they keep adding gaps AND symbols – Joe Dash Feb 18 '16 at 16:27
So how do you (informally) determine what's valid and what isn't? – 500 - Internal Server Error Feb 18 '16 at 16:29
I add them 1 by 1 if its a rival game site? What I want to do is get all the 1 by 1's from a db and sort of remove the symbols and white spaces and try and get the real link behind the symbols blocking it? – Joe Dash Feb 18 '16 at 16:33
You might try checking if a string is similar to an already blocked string through one of these methods: http://stackoverflow.com/a/577551/2622972 – matt Feb 18 '16 at 16:33
