Block IP Pattern (With Spaces)
 
Is there any way to block ips shared like this.

91 87 88 92
OR
91 87 88 92 27015

I saw this in Alka Code, will this be helpful?

PHP Code:
if(digits > 3 && periods > 2)
 {
  server_cmd("amx_kick ^"%s^" %s", szName, reason); 
By the way this is just idea, I would like, Replace Text instead of kick, Replace Text: Stop Advertising !! or plugin made by any means, protects server from such kind of ip sharing, like: Regex if it helps, etc, anything, would be appreciated.

#define PATTERN "(\d.*){9}"
I would recommend you this. It turns true when you've typed 9 or more numbers on chat.
The order doesn't matter.

I don't know about Regex but both of these ideas will return false positives sometimes.

Idea #1: If someone writes 123.. the code will think he's advertising an IP, but he isn't.
Idea #2: If someone writes 123456789 , the code will also think he's advertising, but in fact he isn't.

Ah I appreciate the method but friend, again I have to remind you its request section, not scripting help :p I can't make plugins and it would be better if it turns true after 8 or more, instead of 9 or more.

It's more like of both, anyway the best way for checking regex patterns is using a web-tool called RegexR.

Sorry, just saw your message, yes that's true, but there is no another solution to avoid this !! If you have any idea, please share.

Can you make one? With good idea? So, IPs with spaces can be avoided. Thanks.

I will use it, till yet any other ideas are shared, between can you add message, If IP Pattern found, say: 8 or More digits are not allowed in a single message to avoid IP spam.
+ Can you add Whitelist, so I can whitelist my servers own IPs?
