Thanks, but I’m not sure I understand what this actually does? Is it just making the Contact us link more obscure to spam bots?
In our case I’m thinking some of the spam is human spam so obscuring it isn’t going to help so much. It would also render a captcha pretty useless. The only way to prevent some of these repeat offenders is to ban their email address.
On standard websites where we were getting this kind of spam in the past we created what looked like an auto response sent by a “no-reply” email address to spoof the spammers into thinking their spam mail was flagged automatically by the system as spam.
So we would send them the auto reply email manually which said something like their email violated the general terms of service of the website and was automatically deleted by the system without ever being read by a human.
This of course wasn’t true, and the no-reply addresses was an actual working email address, but it worked almost 100% of the time and the spammers never wrote again. It just takes a bit of manual effort though.
