Competition Spam Sites

I have noticed over the last week or so more mainly competitions are being posted that are being held on sites that will bombard you with spam and sell your details on. I know it isn't the fault of the users who are posting them as they obviously have no clue and just want to help everybody so please don't think i'm having a dig at anybody. After entering comps for as long as I have you get very use to the sites that you really need to avoid at all costs. I thought it might be a good idea for us to have a post where we can share any sites we know that need avoiding . Here are some I know please add any more:

Vaniki- MyOffers - Getmeaticket - Top Fox - OfferX and one that no matter how many times I have told them to remove me from their phone list and have blocked them(they use a lot of different numbers) is an insurance site called Bon Accord Life. Some of the stories I have read about these and the way they hassle old people are absolutely disgusting.

I know there are a few more I have seen but can't think of them off the top of my head but will add them when i remember.
