If you have a specific question we can't work in the dark. We need some information from you at the very least a link. So, you should fill out the Support Request Template Generator and post it back in a new topic to enable us to assist you better.gavinwatson wrote:I have the same problem as has been reported here, but I have the User Registration disabled and do not allow guest posts.
How can they be getting through?
They appear to register (though registration is disabled), then post SPAM and then appear as not registered anymore.
This started happening last week.
Has there been a solution to this?
Well I definately have registration disabled and I had deleted inactive members and they're still flooding through.Angoid wrote:Hi gavinwatson,
Check in the ACP for inactive members .... do you have anything there? Especially spammy-looking ones?
If so, delete them all together with their posts (if any).
Not sure how that affects things, but it's the advice given here and it does seem to be effective.
I'm pretty sure I had a few spam registrations after I turned registration off, but I'm told that this cannot happen. However, I did have some inactive spam members that did not show up on the members list, so I deleted those and the problem appears to have gone away.

The remainder of the registration requirement is controlled by the forum admin: -- the string length, the number of characters to select, and the syntax and wording that the registrant sees.HGN wrote:The problem with such questions is that the format stays the same.

Type character, n, n+1, and n+2 from this string: !@#$%^&*()_+-=":
Only the red parts of the question will be changed by the algorithm. So, program the bot to find:
n ==> between "Type character, " and ","
n+1 ==> between "," and ", and "
n+2 ==> between ", and " and " from"
!@#$%^&*()_+-=" ==> between ": " and ":"
Then use those to determine the characters for the answer.
The door is open for all kinds of techniques to design the "questions" to fool computers but not trick humans. To name a few:
1) Display the string as graphic.
2) Display the character position numbers as graphic.
3) Use the well researched methods that misspell words while retaining readability by humans.

4) Use an algorithm to produce random human-readable misspellings of the words of the question. Thus the words will be unique each time the question is displayed, and destroyed immediately after each usage -- just as with the random strings and random character positions that the question contains.
There are probably many additional ways to formulate the questions to make it hard for spambots to decode them.
The graphic does not have to be Capthcha-style difficult to read, he is saying display the results as a graphic so the bot has another layer to interpret and read.Oyabun1 wrote:Excludes vision impaired users.stanhilliard wrote:1) Display the string as graphic.2)
Yes do, we can see nothing with registration disabled.n8oqpat wrote:I'll change that if you like but I won't leave it that way very long
I see that it is disabled. I am going out the door now, so I cannot look at it until later. I will PM you when I return.n8oqpat wrote:TO: Panzer Max,
The URL to my forum is http://www.uawlocal122.com/phpBB3. It is currently showing disabled. I'll change that if you like but I won't leave it that way very long.
If you read this TOPIC and other TOPIC's on here you will see there is a lot of experience. If you're talking about a MOD then you need to post in that MODs support area.Schwpz wrote:Does anyone in this thread have any experience with the current spam wave and anti-spam measures of the sort "six random images are displayed, tick off the box next to all the images showing a balloon"?
Worse in a lot of cases, phpBB can implement measures to try and stop spam on boards using phpBB software but have no control over other sites, in many cases, anti-spam on other sites aren't as good. You can have the best anti-spam in the world on your board but if you have dual registration you have to consider both.Schwpz wrote:Also, how are forums with linked registrations with Facebook and/or Google+ doing? Hammered like everyone else or any differences?
Try Q&A then, that should be all you need correctly set up.Schwpz wrote:I personally hate filling out captchas
