No you can they actually work still it has been massively reduced though, and the ones still there can be claimed by anybody as long as they rate the site afterwards. That is the new T&C.
If you joined a site in the last week or two which was eligible but now cant put in a claim as it has been removed you can Email firstname.lastname@example.org with the details and it will be manually done. This coming week everyone who has any claims at all should get paid them regardless of minimum amount in the account.
RE The "closing" quote it was going to have none for a month or so then slowly brought back but actually this way is quicker to just strip out all the dead wood. It is nothing like as good as it was though im afraid there used to be about £500 worth its now nearer £100.
