can u get reported for stealing cs or not buying sightstone in bronze 5?

Yes you can get reported. No you can't get banned unless they can prove you made the enemy team profit off of it.

they're gonna report it, but nothing should happen

Yes. Rito has numbers for how much CS every champ can get and if get reported and your CS is above that then you will get punished. If you don't get sighstone on top of that, then you will get a 14 day "last warning" ban.

Reportable? Yes; Bannable? Not really.

If buying a sightstone were mandatory, supports would just automatically be equipped with one.

HAHAHAH ''wandering'' ITS A BARD JOKE HEHE XD

if you're doing it deliberately to screw with your team. then yes. otherwise no

You should mute and report them back (for harassing you with threat of report) just for the irony

you can report for anything, but the system has the ability to filter out false reports.

Not adhering to the META (0CS support, or Sightstone on support) is not a punishable offense.

To answer the question: yes

It will do nothing though.

I highly doubt it. I never buy sightstone as I play aggro AP supports with heavy dmg. How can I get banned for not having an item, lol. Have some map awareness.

I've never heard of someone getting punished for not buying a sightstone.

Everyone has a 3 wards from / / / / , 1 , and also

Riot made this change to force EVERYONE to ward and not make it solely the support's job.
