Hi, relax.
In this instance, I'd let Zaca go with a verbal warning as their spikes were minor and often happened when the user was medding or reloading. The user also seems to have acknowledged it and no one was complaining about them eitherway. When it comes ^EMa^2rie^A030, her spikes were unlike Zaca's, they were major and she was teleporting/floating during the entire replay and therefore should be warned.
In ^A-^9J^No^2h^Cn-'s case, the user was indeed spiking while they were also aware of it but still refused to do any attempts at fixing it, a warning should be given to the user.
