similar to: Deleted Wiki accounts

I have installed captchas on the user account creation page, and hopefully cleaned up a bunch of spam and blocked spammers. However, there is a metric boatload of accounts many of which look random. If you have a legitimate account on the Syslinux Wiki, please put a line or two on your User page; I'd like to eventually go through and delete all the spammer accounts. -hpa

It is by now clear that a handful of persistent spammers have started using semiautomated attacks targeted specifically at our wiki ... one careless spammer even uploaded some of his scripts! As a result, I have switched the wiki to a mode where editors need to be explicitly authorized, manually, before they can edit. As a result, people will need to first create an account, and then get a

Hi, Some people have suggested maintaining black lists and white lists to avoid spammers and allow legitimate callers into the network. However, the problem with this method is that the spammer's IP address might change due to DHCP. Today a spammer might get aaa.bbb.ccc.ddd and lets say that I put this address in my blacklist. To my annoyance, tomorrow a legitimate caller might get

Been working on my anti-spam centos mailserver for a while now and thought I would share fail2ban's help. I installed fail2ban a few weeks back. It was tough to get it working properly but pretty much working now. Although it works fine for brute force, I thought I would run it pretty tough against spammers. I started with a regular mail server, my old one, that is horrendously pounded

I have been using centos 6 in a virtualized system for a few months now. Took a while to batten down the hatches with postfix, rbls, and to use fail2ban correctly. The mailserver for my website(s) are located on the http server as well..an 'all in one' server. DNS servers are separated. My two sites, and their emails addresses (1 for each) have been around for 10 and 15 years

Can anyone with a deployed Rails app recommend a reliable hosted SMTP server that they use? I know that Gmail will let me send up to 500 emails/day, but I have an app that will need to send thousands of (legitimate, non-spam) email per day. I''ve heard that it isn''t terribly difficult to set up my own mail server, but we''re a small company, and as such, we need as small

Looking at http://www.fontconfig.org/wiki/TitleIndex I see it's around 99.9% pure spam. Other than the front page, virtually everything else is the moin-moin boilerplate or the hundreds of pages of spam. Even the Recent Changes & Find Page links have been overwritten by spammers hundreds of times, with the spammers fighting each other to crap on it most recently. (I restored them both

Unfortunately evil spammers have managed to defeat all the anti-spam measures we've tried with the wiki. So it is with regret that we have had to disable new wiki account self-registration. We do still welcome contributions from anyone interested in adding wiki content. We just ask that you send a mail to the main devel mailing list (libvir-list@redhat.com) to request an account be created

I got some spam emails after my last post to the list, and the emails did not seem to go through r-help. The spammers may be subscribed to the r-help, or they get the poster emails from some of the web copies of this list (nabble or similar).

Hello, I am trying to create multiple matrices (to run a PVA) but can't import all of them from a .csv without the numbers treated as labels and not factors. I can enter the matrix slowly: Site05_96 <- matrix(c(0.07,0,0.03,0.00,NA,0.00, 0.09,0.166666667,0.31,0.42,NA,0.00, 0.00,0,0.00,0.00,NA,0.00, 0.00,0,0.00,0.00,NA,0.00,

Re: Per the discussions about spam on this list. Sending a confirming message to an unregistered poster is not a good idea. The return/reply-to addresses in spam is forged, and that is just adding to some victims e-mail. Filtering runs the risk that a legitimate message gets lost, and the sender does not realize it. Filtering is also the most expensive and innefficient way to deal with

I asked the moderators about it. This is the reply "Other moderators have looked into this a bit and may be able to shed more light on it. This is a "new" tactic where the spammers appear to reply to the r-help post. They are not, however, going through the r-help server. It also seems that this does not happen to everyone. I am not sure how you can automatically block the

Hi Chen, In theory, the bare minimum would be to clean it up once in a while, delete the offending accounts and keep an eye on rogue changes. Spam is only the most obvious problem in
