Hello, since I changed Dolphin to UNA, I have more and more users. However, I have doubts whether they are 'real users' or robots / spammers? When registering on my website you have to indicate that you are not a robot so I wonder if there is a way spammers or robots avoid this? They often add posts with external links that seem sensible, I myself wanted to be able to advertise various companies on my website. I do not know what to think. How can you tell if they are spammers? Click here >> you can check on the home page, on the board, how many ads of this type are available, please help.
You need to have the enabled Captcha and you may add the simple question where is the answer will have the fixed length like "Enter the current year" and in Studio->Forms->System->Account->Create Account area add a new field, make it Mandatory and set the Data length as 4.
Thank you, I do it. We will see what the effects will be in the next few days. I still have a question, how to set to enter 2021 in this place? Because at the moment I set any 4 digits and you can enter any four-digit year. Please check here >>
Besides, I have a one more question about the registered ones so far. What do you think about my homepage, can users be spammers and how can I find out? (Captcha has always been mandatory).
Hello again, unfortunately, after my several days of observation, I can say that these security measures did not help (it was quiet only for the first few days). It is even worse and there are more and more spammers. What are other ways to eliminate spammers?
