There's an even easier way - at least in the case of Bloomberg's paywall. Just clear your cookies and it re-sets the counter of free articles you have available. I tried it just now and it works. You don't necessarily need to delete cookies from all time - just however long it's been that you've been using Bloomberg since they put in the paywall (e.g. past week, or whatever it is for you).
Or just google the title. Many of these paywalls are "soft" paywalls, where they dont want to lose that juicy search traffic (most of their traffic).

There is also an option to just delete cookies for a specific website which is pretty useful.
YMMV.
