Google shoots first and doesn't ask questions later. I'm not defending google. I've been anti-google for years. I'm just saying why they disable the account. It's the easiest, automated solution to combat lots of problems like click-fraud, advertiser complaints, etc. If they don't disable the account, they have to constantly handle this type of account, the high traffic, potentially high click-thru, but low conversion attracting account.

The other solution requires making a lot of changes to a lot of accounts. The advertisers' ad positioning, the rates for the ads, which affect other adsense sites, etc. In that case, Google runs the risk of angering a lot of customers, both advertisers, and real estate providers.

The other solution: ban the account -- angers only one real estate provider.
