Some things you can do it you see harassment at a tournament that isn't just directly confronting the harasser (another thread because apparently I like to talk):

There are 3 main strategies for bystander intervention - distract/disrupt, delegate, and direct/confront.

...

Distract/disrupt: do something to distract the harasser (hey you have a match, hey x friend was looking for you, hey come play friendlies with me) or get the victim out of the situation (hey I need to talk to you, hey come play friendlies, hey x friend was looking for you) ...

Distract/disrupt cont: You can check in with the victim at a later time to see if they're okay, if they want to follow up with a TO, or want other support/resources. I like this option because it's a easy non confrontational way to stop harassment and isn't as scary for folks ...

Delegate: find someone to help stop the harassment. Maybe this is a TO one of your friends or one of the victims friends. This is usually when you don't feel safe inserting yourself into the situation. This new person can use the distract/disrupt or direct/confront strategies ...

Direct/Confront: pretty much what you think when you think about stepping in to stop harassment. It's very directly telling the harasser that what they're doing is not okay and they need to stop. It may include explaining why it's wrong (that joke was bad because x) ...

Direct/confront cont. Pros to this is directly addressing the harassment and that there's a possibility the harasser realizes they're wrong and corrects the behaviour. It alsosets a precedent that this behavior isn't o okay. Cons are that it's hard to do this ...

Direct/confront cont: while it's what we think about when thinking about intervention it comes with the possibility of the harasser fighting back at the intervener verbally or physically. It can be scary to start a confrontation which may lead to in action ...

Final thoughts: so while I commend folks who can directly address harassment, I think that many find distract/disrupt safer and easier to do and that's OKAY. Doing anything to stop harassment is good. What's bad is standing by and letting it play out.

Final thoughts cont: don't devalue the pros of getting victims out of bad situations because "you're not addressing the actual behaviour" it isn't hard to go back to the harasser and have a convo in a less stressful environment or get someone else to be w/ you ...

Final thoughts cont: so you feel safer. Distracting in the moment doesn't mean there's no direct conversation in the future. It doesn't mean this behaviour isn't brought up to TOs. It means you're focusing on keeping the victim safe in the moment.
