A tenants' rights advocacy group released on Thursday what it called a "Dirty Dozen" list of landlords from the technology sector that it said had evicted San Francisco tenants.
The list, released by a group known as the Anti Eviction Mapping Project, reflects frustrations over rising rents and cost of living that activists say are driven by the technology industry.
In recent months, grumbling has given way to blockades of the private commuter buses that pick up technology workers downtown and ferry them to their workplaces south of the city at companies such as Google Inc, Facebook Inc and Yahoo Inc.
The list included the chief executive officers of various Bay Area technology businesses, as well as several Google executives.
David Duffield, who the protesters identified as the co-founder of Web-based human resources company Workday , appeared on the list. A spokesman for Workday said the David Duffield identified was not the same as the company's co-founder.
