Making registration for media wiki require admin approval?

阅读更多关于 Making registration for media wiki require admin approval?

问题 A wiki I maintain has been hit pretty hard by spam bots... we don't have a lot of users, and I'd rather not saddle the legitimate users with captcha. Is there a simple way to make registration confirmation go to an admin? I've looked through the manual, and haven't been able to figure out how to do it. 回答1: You could create a new user right, e.g. "approved", allow admins to assign that right and restrict things like editing to only approved users, like this: // Disallow editing and uploading

How to deal with botnets and automated submissions

阅读更多关于 How to deal with botnets and automated submissions

问题 Short story: I have a web application that has a huge incentive for participation. As such, we're being targeted heavily by the scripters and bots. Based on the IP addresses the submissions are coming from (1000+ and growing, no pattern whatsoever), I'm inclined to believe the submissions are being generated by a bot network. Even worse, the person(s) controlling the automated submissions are actively persuing things to the point that every time we make a change, they catch up within a few

Registration spammer detection with akismet

阅读更多关于 Registration spammer detection with akismet

I have a large list of users that registered through a website without any spam filter active during registration. I would like to distinguish which registered users are likely spammers. I'm trying to use akismet to do this but so far akismet is telling me all users are not spammers. Probably since akismet really is made for comments, which aren't available during registration. What I'm sending akismet is the username, email. For url I use the email domain. For their comment, I use: "Hi, I'm $username from $domain registered on $date with email $email and website $url". This however, like said

问题 How to distinguish robots from normal user? How does SO do this job? Currently I'm met with a robot which post once every 1 hour... 回答1: Try akismet as your first line of defense. Bad Behaviour is efficient too, perhaps too efficient, as i had issues with false positives. Akismet on the other hand serves me well. Then, if necessary, add other layers not impeding on the user experience, (like using empty fields that should remain empty) and then if you really have to, other techniques

Spam proof hit counter in Django

阅读更多关于 Spam proof hit counter in Django

问题 I already looked at the most popular Django hit counter solutions and none of them seem to solve the issue of spamming the refresh button. Do I really have to log the IP of every visitor to keep them from artificially boosting page view counts by spamming the refresh button (or writing a quick and dirty script to do it for them)? More information So right now you can inflate your view count with the following few lines of Python code. Which is so little that you don't really need to write a

Stopping spammers from creating accounts (reCaptcha not doing the trick)

阅读更多关于 Stopping spammers from creating accounts (reCaptcha not doing the trick)

问题 Hi we have just noticed a bunch of Nigerian spam accounts in our email system. Now, we do have a reCaptcha in the signup form but apparently they circumvent it, manually or otherwise. It seems like a semi-manual circumvention since the accounts aren't created in bulk but instead as a steady stream with a few minutes in between. Since most of the spam accounts were created by IP addresses from Nigeria, we have just set up some simple IP filters over a couple of pretty broad IP ranges and that

Avoid emails being considered as spam when sent via a PHP contact form

阅读更多关于 Avoid emails being considered as spam when sent via a PHP contact form

I’m using the code below to send emails via a contact form. Issue is that the emails go to the spam box every time (in outlook, gmail, etc). I suspect that this due to the fact that there’s a url (the web page URL) in the body of the e-mail. Therefore I was wondering if there’s some workaround (apart for tagging these emails as non-spam in gmail and outlook) in order to keep the URL (I want to keep it) but have the emails not considered as spam. Maybe by re-constructing the URL so that it does not look like a URL? Surely big companies have tips & tricks for that? Many thanks <?php // Email
