Meh, I don't really care ho9w many warnings someone has had given they give warnings for 'baiting' now by the looks of it. I also suspect Helen still holds the record anyway
If he did something horrendous and just got a warning that would be an issue...but even then it is not a new thing for them to completely wipe all memory of truly disgusting things and let the housemate stay (ala jay mcKray)
