They don't give award weekly but they do update the spreadsheet weekly to encourage their bounty to continue with their tasks, and about awards, they don't get it exactly just after the bounty campaign end. They need to wait for the ICO sales to end, or depending on the forum statement if they said onw or two weeks after the campaign then its good, rules understanding is one key also when to wait or when to complain for your award.
Most of bounty campaign has been opened when the time pre sale time has been deployed on their website. Till that to active sale has been over they will run the bounty campaign. Even after the ICO ends token distribution will not be take part.
There are some bounties still paying the already listed tokens weekly and some bounties pay us along with the ethereum or others cryptos.
New projects do usually comes with bounty campaigns and usually tokens would be distributed in the end of the sale or might able take some time depending on the team thats why dont expect too much on recieving coins as soon as possible because it can take some time.I do only rarely see for bounties which do have already listed on some exchanges and do repeat bounty thing.
