What is meant by the above code??/x*([^x]*)/i[/c]
put this in google:Slackervaara wrote:For those living in countries that has an alphabet with extra letters like Scandinavia and Germany, it can be good to include such letters in the answer. You can have the question: Copy the swedish word for snow snö as answer.
do you think the spam bots have keyboards?Slackervaara wrote:But if you don't have a Swedish keyboard is it difficult to write snö.
Hopefully easy for humans and harder for bots.12 characters is almost impossible to crack, unless they leave the attack on for weeks, Click "PURGE ALL SESSIONS" that should knock the bots off the board if there are tons of Guest visits. I assume the bots will have to start over with the brute force attack on the answer.
I have added reverse questions to my forum with forward questions as well. I realize some don't think this will work, but the larger the string the harder it is to break. If you try the software please comment for improvements and any suggestions to make it even tougher to break through. Still working on multiple question written differently, maybe put string first then the question and then reverse order as well.New version 1.0.0.3
1. Added Reverse Question
2. Use 28 Characters for the string
3. Use at least 4 characters for answer, up to 12 characters.
ODD's Assuming the bot can't read the question and decipher the combination and just the string of 28 characters are attacked. If you just say had 12 character to decipher the amount of combinations of the alphabet the Odds would be below:
12 Characters - 4.35 E+22 Combinations (that's 4.35 with 22 zeros)
11 Characters - 5.64 E+20 Combinations
4 Characters - 35,153,041 Combinations
So reversing and forwarding and adding different types of questions should make it almost imposable to break, so if the string is the only thing it can figures out you would most likely need a distributed DOS of like 3,000-4,000 computers running 24/7 for a few years to break the 12 Characters. Maybe a super computer a few days, but I doubt these cats have there hands on BIG BLUE...
Just Saying...
I agree to some extent and you seem well versed on this subject, all I know when I used the forms of counter measures they are weak and hard to see at least for me, and also easily defeated.stevemaury wrote:I doesn't matter how many permutations there are of the questions or possible answers. Each BOT only has to deal with one question and it can be solved because the instructions tell the bot whether the first and or last characters are needed and how many, and what final or initial character may be disregarded.
There are an infinite number of, for example, addition problems. That does not mean that any one addition problem is infinitely hard to solve.
Anyhow Thanks for your comments and your incite... Cheers Man...Just curious do you use Q&A or the other stuff? Assume you used the pigs and questions like that, and did your board get smoked too? Or where you spared the BS with your solution?
That answer is ambiguous. There are three little pigs, three musketeers (four if you count d'Artagnan), seven dwarves and you (if you call yourself a "critter"). You should really accept 13, 14 and 15.stevemaury wrote:I am going to try once more to give an example of a Q&A that will not be easily solved. I have done this before, and am reluctant for obvious reasons to give too many more, but maybe this will give you the idea.
Q: You have all the little pigs, all the musketeers, and all of snow whites dwarves in a room with you. The total
number of critters in the room is?
A: 14
Sure a bot could solve it, but maybe they aren't programmed to yet. My previous question used exactly the same form, but apparently some human got my question and added it to the spambot's database around 11/21, which is why I got lots of spam on that day.Spammers should be (pick one): Married, murdered, beloved.
It's not ambiguous. Dumas did not entitle the book "The Three Musketeers and Four if you count D'Artagnan". 13 is only correct if somehow you assume yourself to not be a critter, whereas dwarves and Musketeers are.Pony99CA wrote: That answer is ambiguous.

So, if I had the question "Who is Walt Disney"? you would never be able to register at my board?Pony99CA wrote:It's also bad because it assumes a lot of cultural awareness. (Do people in other countries know about the three little pigs, or Snow White and the Seven Dwarves?)
Anyhow for those who tried it please comment...
