I just had a look at the "Cheapest source to get Diablo 3?" thread in "Find me a bargain" (http://www.ozbargain.com.au/node/74226).
I don't have any problem with the actual post, but with the advertisement that accompanied it (address <MOD: removed>).
It's advertising the sale of Diablo 3 gold. An activity that Blizzard certainly doesn't encourage, and that doesn't encourage playing nicely together. In other words, you get caught you get banned.
While I don't play Diablo 3 (yet), I suggest that OzBargain might want to talk to the advertising supplier about what's appropriate. This ain't, and certainly plenty of other websites I've been involved in have taken care to ensure "clean" feeds of ads that are appropriate to their audience.
It's Ozbargain's revenue for Google Ads(generally those who are logged in can't see it)
1) You can disable it through your Ozbargain account(i think)
2) Use a browser add on for Adblock
