Why isn't there a मिटाइए button in my own मतदानो and clubs?

Once a club has been created, it doesn't just belong to whoever created it. It also belongs to other members, and to फैन्पॉप in general. That's why a club can't be deleted. Even if you've लॉस्ट interest in it, there might be others here who like the topic and might want to join.

I think it might be possible to leave a club once you're not the only member, so if others have already joined this might be your best bet. Otherwise, आप can रिपोर्ट the club if it's a duplicate या inappropriate, and get it deleted that way. आप can't रिपोर्ट it for deletion just because आप now think it's a stupid topic for a club, though.

मतदानो are the same way, belonging to all of फैन्पॉप and not just you. I think it's possible to edit/delete मतदानो for a few मिनटों after creation, but not later. Otherwise people would just spitefully मिटाइए any मतदान whose results weren't going the way they wanted.
