But + is rarely picked up by harvesters. It's no substitute for a good spam filter, though (crm114) Sat, 25 Feb 2012 10:12:00 +0000 Jon https://tanguy.ortolo.eu/blog/article45/dedicated-address-spammers/#c1330081623-1 https://tanguy.ortolo.eu/blog/article45/dedicated-address-spammers/#c1330081623-1 This is the reason why web form should use better regex to check email validity... A lot of them declare that my fifou+tag@ adress is wrong after testing it with a bad JS 0_o If you must create a mask to check an email, please read RFC 3696 and http://en.wikipedia.org/wiki/Email_address#Local_part before to create the mask :) Fri, 24 Feb 2012 11:07:00 +0000 fifou https://tanguy.ortolo.eu/blog/article45/dedicated-address-spammers/#c1330073409-1 https://tanguy.ortolo.eu/blog/article45/dedicated-address-spammers/#c1330073409-1 @Tanguy : I don't think the spammers do that but the web sites that give the addresses to them.

I don't say it is easy to count those. Fri, 24 Feb 2012 07:20:00 +0000 claudex
