Here we have a site supposedly offering up prizes for draws - it remains to be seen whether the prizes or the winners actually exist. In exchange you fill out questionnaires - reasonable as an idea. You can expect to give something in return for a chance of winning. When you get an endless stream of telemarketing calls about stuff you have indicated you have no connection to - that is not so good. Basically they are the worst end of the telemarketing business - they are a channel for you being bombarded, harassed and worse, just for their own profits selling 'lists'.
