How to Block Users From Reattempting a Survey & Restricting Spam
You can block your users from reattempting a survey so that they may not provide contradictory answers for the same experience. This is helpful in maintaining the genuineness of the information provided by the survey takers.
There's another risk with online surveys and that's of spamming. To ensure that your users are real and not bots, you can use the Captcha setting. It prompts the users to tick certain images from a gallery of images. You will be able to submit a survey only after ticking the correct images.
Step 1: Go to a survey's Settings >> Security.
On this screen:
1. Enable the Block setting.
2. Once enabled, it provides the following options:
- Block by computer: Any reattempt with the same username will be blocked.
- Block by IP: Any reattempt from the same IP, irrespective of the device, will be blocked.
You'll get the following message on trying to open the survey after enabling Block by computer or Block by IP.
3. Enabling the Block option automatically disables the option Attempts Allowed Per User. This is a natural course of action since you're blocking reattempts entirely.
4. Total Attempts Allowed: This indicates the total number of attempts allowed for a single survey, irrespective of the number of users. For example, you've set five attempts for a particular survey, as shown in the screenshot above. Now, those five attempts can be utilized by a single user or five different users (one attempt for each user). Once those five attempts are done, this particular survey will no longer be available for the taking. Once you're done with all these settings, save.
This is the message you'll get on trying to access the survey after using the number of reattempts allowed to you.
Spamming is a major issue that can compromise the authenticity of the data you collect through your surveys. You can avoid this problem by activating the Captcha setting.
Step 1: Under the Security tab, locate the Captcha setting at the bottom and enable it. Once done, save.
This is how the Captcha appears in a survey.
