Did you know that Sex Workers Outreach Project has a prison letter writing program? You can easily sign up to become a pen pal with a criminalized sex worker on their website. They don't ask for very much personal info, just a name and email, and country/state you live in. They also have a return address you can use if you don't have an address you feel comfortable using for prison mail. If you've been considering letter writing this is an easy way to connect with people who often don't get as much support as higher profile political prisoners!
