The agency said that reports have grown since last week when Black people were targeted with messages from anonymous phone numbers.
Summary
The FBI is investigating a surge of anonymous racist and offensive text messages targeting Latino, Black, and LGBTQ communities following last week’s election.
Messages have included threats of deportation, re-education camps, or being forced into plantation labor.
While no violence has resulted, the texts, sent via services like TextNow, have prompted collaboration between the FBI, DOJ Civil Rights Division, and local authorities.
Advocacy groups like LULAC and the NAACP condemned the harassment, citing it as a troubling resurgence of hate rhetoric emboldened by recent political developments.
Another poster suggested a Russian disinformation campaign, I would suggest a more home-grown hate faction that was grown from the poll-watcher contingent. They culled and sifted lists of people that were most likely to "spoil the vote" and had nothing else to do do but harass people.
