no spaces in subject

[hsfrey]

I'm getting drug spams with all the subject line letters run together and no spaces (kind of like German ).
They aren't recognized as spam.

Does anyone have any suggestions about how to write a regex to recognize a string over (say) 20 characters with no space characters?

I could probably do it if I could write a few lines of javascript, but I understand that the rule has to be one regex. Is that right?

Hello hsfrey!

This one should work:

Code: Alles auswählen

\w{20,}

But it sounds pretty risky to me, asking for false positives.

Thanks Quellcore:

Regexes always seem so obvious when someone else figures them out.

As for false positives, I doubt that, at least in English, I would be likely to have a word 20 characters long.

And if it did, wouldn't it end up in my training area where I could catch it?

Correct, no problem then
Could you give me an example of one of those long strings
Do those spam specific long strings contain only letters or also numbers
How about all the special characters like !@#$%^&*()-_=+{}[]\|;':",>,./?
If you want to allow any non whitespace (= anything but whitespaces) character to be part of the long spam word this might be the better expression:

\S{20,}

Please note the captial 'S', it has a different meaning than the non capital 's''.
