Read the question carefully.
Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.
If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Insults are not welcome.
Don't tell someone to read the manual. Chances are they have and don't get it. Provide an answer or move on to the next question.

Solution 1

Simply you can track that user's IP and e-mail Id and while saving new survey check whether these details already exists in the DB or not. If exists dont allow to save.
