GroupM, IPG and the Omnicom Group have reportedly paused advertising on Twitter.

Some of Twitter's largest advertising clients are being warned that the platform is 'high risk'.
Reports say that GroupM, a leading media investment company, is warning clients against advertising on the site.
Other worldwide agencies such as IPG and the Omnicom Group, have also recommended pausing its adverting plans with Twitter.
Concerns over 'parody' accounts and the firing of those in charge of safety, security and compliance are rising.
According to CNBC, Elon Musk’s space company recently bought a large advertising package on Twitter to promote Starlink satellite internet in Australia and Spain.
With an estimated volume of 250,000 US dollars, it's not enough to even come close to counteracting financial worries the site now has.
