Word sequence

What will be the regexp to block a specific word with any syntex,
i.e.
someword
s o m e w o r d
so me wo rd
s_o_m_e_w_o_r_d
(s)(o)(m)(w)(o)(r)(d)

anyhow if they use that word with any syntex it will be blocked, Shall i use some thing like *s*o*m*e*w*o*r*d* ? Thats what i use in ban nick block in unrealircd.conf

Can anyone help me out?

Thanks.

Well i tried this command:

/spamfilter add cpnda gline - - *s*o*m*e*w*o*r*d*

The resault was

-irc.deshikotha.com- Error in regex '*s*o*m*e*w*o*r*d*': Regular expression is too broad

Read the documentation. It clearly states that regular expressions are not the same as glob matching (ie wildcards, what you're using).

try /spamfilter add cpnda gline - - ^.*s.*o.*m.*e.*w.*o.*r.*d$

(excuse my poor regex skills guys, feel free to correct me.)

I need another information

The solution is perfect. but the problem is when some one add something infront of it or after it spamfilter is not doing anything. i.e.
i have added word "someword" in spam filter. but if some one type irc.someword.com spamfilter not doing anything. Is there any solution?

Thanks.

Take the ^ and $ off the regex.

I put them there to reduce the likelyhood of false matches.

Actually, you didn't need those to prevenet false posatives... All you needed is:

Code: Select all

s.?o.?m.?e.?w.?o.?r.?d

Yes, but then what stops things like:
so43meword

If you see any of those, add more .?

You don't want .*, because that can create many false posatives... such as "f.*u.*c.*k" will block such things as "firetruck", as "f.?u.?c.?k" won't.

True... but... >.>. Ok. Maybe the docs should then be changed to reflect a recommendation of ? over *?

Maybe...

Thank you stealth and w00t

I am using s.?o.?m.?e.?w.?o.?r.?d regexp. I think its perfect for me.
