Using an internet forum for Social Research

[Vuk]

I have decided to conduct an Org poll where users will tell their professions and vote on their diet preferences. I will then tabulate this data and arrange it by professions, so can tell which professions like which foods. I will then use this data in my Uni research paper with the following entry under the "Methods" header:

"This data was gathered on an internet forum on which it is possible for a single person to create multiple accounts (and therefore vote multiple times) as well as for bots to register and vote. It is also impossible to know if the information given is accurate or not, or if the people are really who they say they are. Therefore this data is completely useless and should be completely ignored."

What do you think, is it a good idea?
