For what I can see here regarding points and the recent w/l ratio it doesn't seem like swapping actually for the way they go in the last 15 cws they played

However, checking more deeply into this and checking the CW logs is pretty probable that they are swapping, specially those involving the player you named, GunaShekar, the won more than what they lossed in a serious big difference hard to get without doing swap so it's pretty sure this is a swapping case in what regards "LoveIsBack" since they share members and being on same place.
Regarding the other clans liken Ocean it's clearly no swapping due to that they aren't even from samw country.
This is a YES for me regarding LoveIsBack and they should get those points removed, regarding Ocean or Aura it's a No, and regarding the last cw against Hatol, I'll leave this to my fellow TGMs and to the official's judgement.
