About

Block Party provides middleware that integrates with Twitter's API to automate blocking, curate block lists, create a Lockout Folder for reviewer/helper access, and offer free and paid filtering tiers.

Mission

Block Party, launched in early 2021 by Tracy Chou, provides middleware that lets users automate blocking bad actors and create curated block lists on Twitter. The product builds on Twitter's API and offers both free and paid tiers; free users get features like moderate filters while paid subscribers unlock keyword filters and a helper view for shared account management. Users include public figures and smaller accounts seeking stronger privacy and safety controls. Twitter proactively engaged with Block Party to ensure the services can work in tandem. The company has a team of four full-time employees and plans to use its seed funding to expand to other social platforms. The business positions itself as third-party tooling that lets individual users control what they see without relying solely on platform moderation. Block Party, founded by Tracy Chou, is an anti-harassment startup that currently integrates with Twitter to filter unwanted content into a Lockout Folder for later review. The product lets users grant trusted helpers access to that folder to assist with flagging or blocking trolls and to share the burden of managing abuse. The Lockout Folder also serves as a record-keeping tool for reporting harassment to platforms, lawyers, or others. Block Party emerged from Chou’s experience at platform companies like Facebook and Quora and her work on DEI issues. The service is currently free; the company plans to introduce subscription tiers while keeping a free version available. To date the company has raised a little less than $1.5 million in funding.
