Keep a tally on everyone who is being disruptive, even good friends. Don't expect wreckers to go>Hey guyz did you know Nazi stands for national SOCIALIST WORKER PARTY 0_0; ???
Nobody irl or even in a private online group is going to do comical shit like that. Look out for stuff like>dragging conversations into pointless directions
Don't expect wreckers to go "HUUUURRR LETS TALK ABOUT IDPOL LOLOL!!!!", it's not (always) gonna be blatant like that. There is a huge difference between planning to help local unionizing efforts and talking about how bad corporations are for union busting. The later might be more fun but it also gets nothing done. >relationship-drama, (cry)bullying, pointless personal fights
Always try to keep a close eye on the social dynamics of your org. If a member is constantly involved in drama or being the focal point of conflict between members then there is a good chance that it's not a coincidence. Seriously don't underestimate this shit, it can destroy any group.>clique formation
While this happens naturally in every larger group, be aware of cliques that are formed to specifically undermine your org. For example, lets say you have a rule that says "We are not going to talk about class reductionalism in group meetings", so a bunch of members gets together to talk about class reductionism outside of group meetings and invite other members to join. Shit like that is going to lead to huge problems down the road so it should be shut down as early as possible.>pointless calls to (illegal) action
This should be self-explanatory but be very aware of people who constantly speak of breaking stuff or attacking people, especially when they leave a paper trail by posting that shit in group chats.
If you keep the tally long enough you'll eventually be able to spot highly disruptive members. And even if there is no wrecker who is intentionally trying to ruin stuff, by looking out for this kinda shit you can spot retards and shitheads who cause more trouble than they are worth.
