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.
我记得我们最近在这里将限制从 50 个字符提高到了 100 个字符，其他人有印象吗？
我不确定自一月以来是否有变化，但在启用“启用 Markdown 链接化”设置时，这似乎只能部分生效。
正则表达式可以完美地屏蔽文本，但电子邮件地址会先被解析并转换为 mailto 链接，导致电子邮件地址在 HTML 中暴露。
例如：
<a href="mailto:someone@example.com">■■■■■■■■■■■■■■■■■■■</a>
如何做到这一点？我到处都找不到启用正则表达式的方法——如果我尝试使用它们，它们就无法工作。
