We don’t want users posting emails. Is there a way to achieve this?
Thanks!!
We do have a censoring mechanism, but it’s based on words.
Your best bet would be to write your own plugin 
Also could you just make it a site rule not to do that? And have moderators remove it if it happens?
We haven’t had a problem here with people posting many email addresses.
It’d also be a problem when allowing anonymous emails into the a new topic … the sending email address is posted above the incoming message.
yeah, it is a Pets site, and people start posting their emails about free dogs or cats, which are usually fake. We delete them manually, but still would be good to have an automatic rule for emails.
If you can teach your community to flag these posts as spam when they see them, I think you’ll be pleasantly surprised at how easy it becomes 
censored pattern = \d{3}-\d{4}|[\w+\-.]+@[a-z\d\-]+(\.[a-z\d\-]+)*\.[a-z]+
will censor xxx-yyyy phone numbers and email addresses.
Does the above pattern work for anyone else? I tried entering it and got a “Sorry, an error has occurred.” alert. Even with just \d{3}-\d{4} and regular expressions turned on, it doesn’t block 123-1234 in a post. Was there a change, or am I doing something wrong? Thanks!
Where do I enter that?
It moved.
Navigate to /Admin/logs/watched words
I think you also need to enable the option regex for watched words in the settings.
Doesn´t aceept the expression, to long, error says maximum 50 signs. I tried to enter it in censuring
I’d like to express my support to anyone who could fix this “issue” too: previously the official RFC 5322 (426 characters) could be entered to hide any email address. Now it’s only 50 characaters max.
Maybe now there is another better way to obfuscate email addresses (especially to crawlers)?
I second the idea of increasing the character limit here. Regular expressions can easily get past 50 characters.
For the watch words, it would also be nice to have a description field so when there is a regular expression in there, it is easy to know what it should be doing.
最近、ここでの制限を50文字から100文字に引き上げたと思いますが、他の皆さんも覚えていらっしゃいますか？
1 月以降に変更があったかはわかりませんが、「Markdown リンク化を有効化」設定が有効な場合、この機能は半分しか機能していないようです。
正規表現はテキストの伏字化に完璧に機能しますが、その前にメールアドレスがパースされて mailto リンクに変換されてしまい、HTML 内にメールアドレスが露呈してしまいます。
例：
<a href="mailto:someone@example.com">■■■■■■■■■■■■■■■■■■■</a>
それをどうすればいいですか？正規表現を有効にする方法が見つかりませんでした。もし試しても機能しません。
設定名は「監視対象の単語の正規表現」です
