spam prevention?

Recommended Posts

Why don't you all use the spam prevention tools?

On my forum one must answer a question that any kayak or canoe paddler would know to register. Got read of the damn Russians!

I think your registering question is weak. I would ask a question that requires a Yahoo search. Perhaps the spam computers could not do that.

Like what is Pi to the 6th decimal place?

Something like what is the:  "unit of capacitance"a five letter word". It is only a slight inconvenience at most for real people plus they only have to do it once.

I set up a forum earlier this year and asked the local padding group if they wanted to use it but they decline. I did not do anything with it for a few months until I got an error message via an email. When I looked at it I had 6800 members, 90% were Russian. As I could only delete 30 members at a time it took awhile to get rid of them.

Can the bad guys login via "Sign in with Twitter or Linkedin"   or  Anonymously thus avoiding the question?

They are mostly registering as a plain user, they pass the question, automatic Spam Defense which flags the accounts with spam score and they also approve their email address which is new each time.

If you open the register page and right click on the page and select "view page source" you see the html code that makes that page. If you search on that code for: "form_q_and_a" you will find the block of code that renders that area on the page.(in firefox search by ctrl+ f) and that contains your question. If one is comfortable with working with files on the server one can find the file that contains the "form_q_and_a" string. then download it to your pc and replace the text string with an image ( jpg or png file ) of the text in mixed colors and fonts.

If you don't have the tools to create such a file I do. You may not see you  text string  in that file as  it maybe added in at run time.

In my first forum I got to the point that I would register members via an email request myself; they where not allowed to do so. I used their requested user name and assigned them temp.password and that works well if you do not have many request per day. It beats having to clean up the forum everyday.
