Twitter should address cyber squatting

I've only checked asdajobs and tescojobs on Twitter but both have been hijacked by Check4jobs; I'm sure they are squatting on many more names so both Twitter and the brand owners should take action to block them.  They should also block them from scraping jobs from their sites as well. 

It is this kind of underhand tactic that gets the recruitment industry a bad name and forces changes that will result in big brands charging the job boards to display their jobs/brand.  It is also up to the original advertiser where relevant to stop this kind of activity.  I'm all for jobs being aggregated where permission is granted but taking a brand name on a site such as Twitter is totally out of order.  So Check4jobs; we will be on your case!
