Hello guys,

What is proper regex to filter out empty characters (spaces) string of any length. More spacific if someone someone post "_" or "____" or "________" etc (_ is space) that would be filtered however when someone go for "_hello" or "_hello_there_" etc that will pass. So for example:

/spamfilter add cN block - Empty_string_detected. <someregex>

What should be used for <someregex> to fit this need? I hope this should be easy for people familiar with regex syntax which unfortunately i'm not.

Many thanks in advance and happy holidays everyone.

Try:
^\s*$

Which will also match "" too.

Thanks Jobe1986 however:

Error in regex '^\s*$': Regular expression is too broad

I've tried with badword block (with idea to mlock +G later on channels where i need this) but with the same type of error. :/

Match: " {2,}"
Replace: " "

Solved with "^ {1,}" to "" for what I needed. Many thanks everyone!

edit: changed to better and actual solution.
