For Chrome:

“Plan B or "Infinite Bing Reward Points" Exploit Exploits and Stuff”
If you don't feel like cheating sketchy websites, then here's the 10-day solution to getting 136 keys:

Make a Bing account (it's worth 4 keys as well).
Once you've done that and set it up, click "Invite Friends" and copy the referral link it gives you.
If you're using the same browser you'll have to log out of your Bing account first.
Use the link to make another new account.
Do all of the free Bing rewards things that it gives you.
Make 30 bing searches a day for 10 days to accumulate 200 Bing reward points. This will put your account into silver status, which will give your previous account 500 free Bing reward points.
Redeem your points for the "500 SwagBucks" reward.

Congratulations, you now have over 450 swagbucks!

If you're feeling bored, make a chain of 10 Bing accounts that referred eachother, then get 200 points on the last account. If it works, you should suddenly have 10 accounts with 500 points each, equal to about $50 of Microsoft points or whatever else you want.
I haven't tested this yet, but in theory why wouldn't it work?
