zoopla.co.uk é seguro?

A post by Shazza on 3 February 2012 noted that ***** had no property listed on the site. It seems the site had only recently been launched at that time. Now (4 July 2012) the site seems to have quite a few properties listed. I can't tell if these were added to the site manually, or if they are populated by pulling listing data from other real estate sites. Yet, either way, the search mechanisms seem to be working fine. I investigated the claim by B007 from 29 June 2010 stating that there was spam from Zoopla here on MyWOT. I searched for Zoopla on MyWOT and found nothing. I was told there's no record of spamming here from Zoopla. Here's the forum discussion about this *****
