The chief information security officer of Twitter is reportedly leaving the company.

The Verge says that, according to sources, Twitter Chief Information Security Officer Michael Coates internally announced that he was stepping away from his role three weeks ago.  But currently, there has been no eternal announcement.  Supposedly, he is leaving to start up his own company.

This doesn’t appear to be to be just a twitter issue either.  This has been quite a week for top-level security executives at various technology companies.  On March 21, it as Michał Zalewski, Google Director of Information Security Engineering & Assurance announced on Twitter that he chose to leave after almost 11 years.  News broke on March 19 that Facebook Chief Security Officer Alex Stamos would be leaving the company.

The reason why technology platforms are having such issues is because they’re being accused of allowing misuse and abuse o their platforms leading up to the 2016 US presidential election and mounting pressure to act.  Twitter, for its part, chose to make policy changes to curb spam and bot activity by restricting simultaneous tweets form multiple accounts.  Twitter has, for a while now, accused of not addressing abusive and malicious behavior on its site.

Coates joined Twitter in January 2015.  According to The Verge, his interim replacement will be Joseph Camilleri.  He currently serves as Twitter’s senior manager for information security and risk.
