Could someone lead me on finding a regular expression that blocks a comma separated list of Spam words I already have?
The regular expression needs to match a string with the spam word list I already have.
Not that it matters, but I am using PHP.
I want to have an admin page to manage user messages reported as 'spam'. I know how to use MySql and php to have a list of messages reported but I don't know what is the more safe way to access to this page. Local, https,...

My Heroku (Bamboo) app has been getting a bunch of hits from a scraper identifying itself as GSLFBot. Googling for that name produces various results of people who've concluded that it doesn't respect robots.txt (eg, http://www.0sw.com/archives/96).
I'm considering updating my app to have a list of banned user-agents, and serving all requests…

I'm usually overwhelmed by the amount of tools that hosting companies provide to track & quantify traffic data and statistics. I'm equally overwhelmed by the countless flavors of malicious 'attacks' that target any and every web site known to man.
The security methods used to protect both the back and front end of a website are…
I've had my domain (straightpathsql.com) for a few years now. I host my e-mail with Google Accounts for business and have for awhile. ALl of the sudden in the past week I am starting to get a lot of postmaster delivery fail notices from various domains, most of them involving bogus e-mail addresses at my domain…
I have been attacked for weeks by the same spambot trying to brute force the login page. I have a login security module now installed on my Drupal 6 website and it bans on IP after x amount of attempts. It's been going on for ever and I have banned about 1000 IP addresses.
Is there any point in me banning on…
Has anyone come across a crawler called Grapeshot? They are hammering the same page repeatedly on our website. I believe they are looking for ad related keywords, based on previous content ad campaigns. The odd thing is we never ran any such campaigns on the page they are so interested in. We do have only a…

I'll give an example of one that I've noticed: the number of web sites that ask for your email address (GOOG ID, YAHOO! ID, etc.) has skyrocketed.
I can come up with no legitimate reason for this other than (1) password reset [other ways to do this], or…
Recently I, along with the rest of the world, have seen a significant increase in what appears to be scraping from Amazon AWS-related sources.

I have a small community forum that doesn't really get posts or any real traffic. The only thing that happens on the regular is bots with Chinese IPs signing up gibberish usernames. Most bots don't make it past the captcha but some do. I try to stay on…
