I need to distribut my PhD research among English native speakers communities

I have my current PhD research and I need English Native speakers to take part in a language questionnaire. The thing is that I need to emphasise on something. There are some people think that they help me by merely choosing the same answer THOROUGH the survey which is something that destroys my research. I need reliable responses and share the following paragraph, please.
Here it is:

Dear All,
I am a PhD student at the School of English Studies in Nottingham University, UK. I am looking for native speakers of English and native speakers of Arabic who speak English to take part in a language questionnaire. The aim of the study is to investigate your knowledge with regards to the use of word combinations in English. Here is the link:
