The “free gem” bots that are ruining my clan, your clan, and everyone’s clan.

[George1971]

And what about false reports from trolls? What if I'm a legitimate player and I made some angry for whatever reason, so that person makes a false report that I'm a spam bots and I need to jump to my sister clans. Am I barred from entering my clans until someone investigates the report?

There are so many ways of dealing with this issue.

you set the threshold for reports of spam. Eg five reports to have the spambot locked.
You count the spam reports that are true and false. Troll reporters lose their credibility, or can even be punished in game.
Supercell need to assign Human Resources to reviewing spambot reports. At the moment their is no report classification at all, most are probably “he was rude” and a waste of time for supercell.

If you are long term in a clan, you should be troll proof. Only your clan mates could report you, and the game data knows your recent clan movements. A plausible spambot would be an extreme hopper.
