we don't remove them ourselves for anyone unless they were wrongly warned, you're mistaked about that. and points accumulating doesn't mean we band you. if you double posted four times and have four warnings from that we dont say "oh they have four warnings ban them". we look at what they're for. now, if there are like 8 or so warnings for something minor like double posting, then yes, you will probably have a one day or so ban, because at that point you're just ignoring us.
no reason to get so worked up.
and yeah, we don't automatically give warnings, especially not for first offenses. i personally with smaller things send reminders and only up warnings after the first (or depending on what it is, second) offense.
