These updated threads are annoying to us regulars on the forum and we have seen them all 100 times.
But they are not targetted at us. We are already customers or have already made up our minds about certain shops.
The updated threads are aimed at newbies and more importantly guests.
Check the people on the forum info and you will see guests outnumber members 5 to 1.
These people are often seeing the thread fir the first time. And there are always new guests logging in to view them.
That's why some threads have 1000's of views.
They may annoy us regulars and we just ignore them, but they are clearly an effective way to advertise the agency/shop to new customers.
That's why advertisers will keep on doing it - its good for business.
