Hello, I took the first corner and got a claim next to me.

You may report that faction for "Claim Hindering" here
Make video evidence showing the /f map (as in your image) and make sure to perform /f who on both of the factions and include it in the video. Upload this video to YouTube and attach the link as the evidence

I checked your evidence and it's totally valid to get the claims removed.
Make a faction report here: https://pika-network.net/opf-report/
The claims should be removed soon when your evidence is verified by the team factions.
