PEOPLE have voted by more than two to one in favour of a fixed link with the mainland.
In the survey, commissioned by the Pro Link campaign, 66 per cent were in favour, 29.1 per cent were against and 4.9 per cent were undecided.
When it came to a full feasibility study, people voted by more than three to one in favour.
Organisers said the purpose of the survey was to establish whether people were in favour of a study to see if a tunnel could and should be constructed under The Solent.
The six-week questionnaire closed on March 31 and organisers admitted while it was set up to enable only one response from each computer, they were aware some individuals found a way of making multiple responses.
But report author, professional survey organiser Ian Butcher said: "The level of attempts to discredit the survey and skew data by a few individuals has been relatively easy to detect.
"Their behaviour shows disrespect for genuine individuals who have contributed their views on either side.
"I believe the data in the final cleansed report represents as far as accurately possible the data from genuine contributors."
Responses from Mori Gallup, Fred Dinenage, Frank James, Theresa May, Donald Trump and people purporting to be pro-fixed link campaigner Carl Feeney and members of his family were weeded out.
He defended the framing of questions against allegations of bias and said he believed most people taking part had given honest answers.
It showed nearly 60 per cent of those participating were aged between 30 and 60, with only 4.7 per cent under 20 and 17.9 per cent between 20 and 30.
Isle of Wight residents outnumbered those from the mainland by seven to one.
Most of the report’s 346 pages are taken up with the views of those taking part about the potential effect on the Island’s economy, accessibility, environment and quality of life.
Mr Feeney, who has campaigned for two-and-a-half years for a fixed link, said: "It is impossible for people to make an informed decision until there is a proper, impartial, feasibility study. It is that study we want.
"The DfT is prepared to carry it out but the support for it is needed from the Isle of Wight Council. Constructive meetings have been held and I am hopeful for that support after the election."
