Yes, I realize this question was asked and answered, but I have specific questions about this that I feel were not clear on that thread and I'd prefer not to get lost in the shuffle on another thread as well. Previous threads said that rendering the email address to an image the way Facebook does is overkill and unprofessional user expe...
The ways I can think of are: Measure the time between actions. Compare the posts' content (if they're too similar to each other) or, better yet, only the posted links. Checking the distribution over a period of time the user is active (if the user is active, say posting once every hour, for a week, then either we have a superman ...

Let's say I want to create a reusable REST web service that allows checking whether a piece of text/ blog comment is spam, once for all. (sick of adding this feature in every web app I work on) Which tools, libraries, frameworks, that would nicely integrate to either Java or Python, would you recommend to accomplish this ? Thanks ...
Hello, I have a mongrel server running behind Apache. It works fine; however, every now and then the Apache server shuts downs seemingly by itself. I'm not sure if there is configuration issue or if it's an attack. Here is Apache error log: [Thu Apr 30 02:15:07 2009] [notice] SIGHUP received. Attempting to restart [Thu Apr 30 02:15:0...
Hello, I've already read most of the questions regarding techniques to prevent form spam, but none of them seem to suggest the use of the browser's session. We have a form that sends an email to given email address and we didn't like the idea of using "captchas" or Javascript, as we wanted to keep the user journey simple and accessible...
Folks, I have an html form which sends the form data as an email. Unfortunately spam bots have been filling the form in and send web site links and email addresses in the message part of the form. Is there a way I can delete the web site links and email addresses when the "Submit" button is pressed before it gets sent on as an email ad...

I assume it's bots, or something like them. We have forums on our website and daily we get 1000's of attempts to post spam. These never actually make it into the database, usually by throwing a ViewState or EventValidation exception. I'm not sure if I should even really be concerned. I'd really like to do something about these bots. ...
I'm working on a site in which users can opt-in for email notifications for various events (think Google Alerts). An early version of the site had a problem that accidentally generated hundreds of emails to the same few test users. That bug has since been fixed, but leads to the question: what are some recommendations for ensuring that c...
Technically this might not be classed as a programming question, since I have already implemented a solution. But it's an interesting issue in the tech field nonetheless. Anyway... I set up a basic contact form, without any spam protection. On discovering that it wasn't working, I ignored it and set up a Javascript to change all links p...

I'm writing a forum application but one of the things I'm concerned about is trolls - users who disrupt dialog with abusive speech or off-topic content. This goes beyond spam prevention because it includes people who are actually participating in a discussion but who either refuse or are unable to follow proper standards of behavior. Wi...
I've been having a spam problem on my site, where people sign up and act extremely abusive to other users of my site. I can easy IP ban them, except they always come back under a different IP address through a proxy or TOR. So I was curious if there are any php classes or functions that can look up the IP and determine if its a genuine ...

The only caveat being that you need to go through their interface and their database/algorithm is not open sourced or readily available otherwies.

I'm building an email newsletter service. Obviously we are doing regular opt-out links and everything like that, but I'm wondering...when a user in Gmail does the "report spam" button (or equivalent in any email client) how can we receive these reports?
