The team is officially off in the summer. The team chat goes quiet. The Instagram account stops posting. But the parents and the kids keep using social media, and what gets posted in June can detonate in August.

Three rules that hold up.

Don’t post photos of other people’s kids without permission. This is the one that breaks most often. The parent who took photos all season uploads a season-recap reel in June with everyone’s kid in it. One family has a custody arrangement that means their kid can’t be in posted photos. Another family is dealing with something private. The reel goes up, the texts start flying, the relationships sour for fall.

The rule is simple: ask before you post. A “hey, planning to share these end-of-season photos, let me know if any kid shouldn’t be in it” group text takes 30 seconds and prevents a year of weirdness.

Don’t trash the team or the coach on Facebook. The summer venting on a personal post about how badly the season went, how unfair the coach was, how the parent culture was toxic, it gets back. Always. The screenshots travel. By August, the coach has seen it, the team mom has seen it, and your family is now the family with the post.

If you have to vent, vent to a friend in person. The internet is forever and the youth-sports community is small.

Don’t post the new team selection or roster news before it’s official. When tryouts come back in late summer or early fall and your kid makes the team, sit on the news for a day. The coach hasn’t sent the official announcement yet. Other families are still on the bubble. The early “we made it!” post is rude to the families who didn’t.

Tag and credit photographers. If a parent takes the team pictures and shares them in the team Drive, credit them when you repost. Costs you nothing, prevents the small-and-real resentments that build over a season.

Keep the kids’ faces off public-facing posts when you can. Locked accounts are different. Public Instagram, public Facebook, public Twitter, once it’s up, it’s findable forever. Most parents are casual about this. Some kids will resent it later. The default of “ask first, post less” is the right one.

The team’s offline reputation can be hurt online faster than it can be repaired. The summer is when that happens.
