This is a really important point (and also a tactic that antifa have used from time to time)! In our post about joining an antifa group/starting your own, we warned people to approach any group you’re not familiar with caution for just this reason. Here are some tips:1) Research the group you’re thinking about joining up with. If they have a social media presence or website, how long has it been up - a short while or a much longer period of time? Have they been involved in any antifa actions that you’re aware of? Are they linked with other antifa groups you know of? More importantly, do those antifa groups vouch for this one? Is this group part of or affiliated with an antifa network like The Torch Antifascist Network (U.S.), or the Anti Fascist Network (UK) or La Horde (France) or Antifascistisk Aktion Sweden or Anti-Fascistische Actie (the Netherlands)? Has the Twitter crew @antifachecker listed them as a legit crew that they follow or a fake-ass crew of fash trolls that they’ve blocked? 2) Be careful what information you provide at first. Most antifa groups will probably want to know how to get in touch with you, what your name is, where you live, why you’re interested in getting involved, etc. But you can see how revealing too much - your full name, your neighbourhood or home address, where you go to school or work, contact info that can be traced back to your home - can be used against you if the group turns out to be a trap.3) Meet in a public place. When you’re first meeting with members of the antifa group you’re looking to join, meet them in a public place. This protects both of you, as things are a lot less likely to kick off if you’re in public and there are a lot of people milling about. That said, you also want to meet where everyone will feel safe to discuss matters openly. We’ve found that many cafés or pubs serve this purpose quite well.4) Bring someone. If you’re looking to get involved in antifa, you probably know someone else that is as well. Bring them, or even someone not that interested but who you trust and who has your back. There really is safety in numbers!5) Tell someone where you’re going. Make sure someone knows where you’ve gone to meet up, when the meeting is, and when you expect to be back. Better yet, do all of that and tell them that you’ll call them 15 minutes after the meeting begins to let them know you’re ok. If they don’t hear from you then, it means you’re in trouble and need help. BUT DON’T FORGET TO CALL THEM @ THE 15 MINUTE MARK!6) Trust your instincts. Boneheads aren’t very good actors. If anything doesn’t feel right to you; if something seems suspicious, walk away. It will be a lot better to explain yourself after the fact if your instincts were wrong than to find yourself in a very bad situation. Look, we don’t want to make anyone overly-paranoid - tbh, these kinds of things do not happen very often (we can’t think of a single instance of this happening IRL with any antifa that we know personally, although as the original poster mentions it’s been known to happen), but in antifascism, as with all political activism, it’s best to take sensible precautions.
