The details of these re-vitalized but historical 2011 neighbourhood-level crimes, already got significant media attention. More will come. Deciding the civil cross-claims is still incomplete.
Whatever the eventual judicial outcomes, the arsonist perpetrator S.E. has brought forward some health & lifestyle explanations or grounds for sympathy.
And another conceivable argument in her favour :
that having totally paid her criminal & civil justice penalties, maybe should arsonist S.E. get a blanket of anonymity from her victims & maybe from others ? Or at least eventually ? Shouldn't healing be allowed to occur ?
Several issues :
1 - Was the 2016 "outing" to S.E.'s new neighbours, unfair harassment or defamatory hurt-speech or whatever civil wrong ?
Would it make a difference that the "outed" crimes occurred 4 years earlier ? Or 14 years ? Or 24 years ?
Is the nature of the historical crimes relevant ? (
S.E.'s of course wasn't removing a Do Not Remove label. Hers were unprovoked autumn 2011 death threats to a neighbour she did not know, followed shortly by a night of vandalism & what easily could have killed K.T and her sleeping family ! The 2016 new neighbours arguably could meet exactly the target, totally out of the blue . . . )
Restated, should non-malicious, truthful “outing” ( by victims or others ) expose to liability for harassment and/or defamation at least IF the sting of hurtful speaking cannot successfully raise the usual defamation defences ?
2 - Are criminal perpetrators generally entitled to some sort of blanket anonymity after formally discharging criminal & civil penalties fully ? If so, what ?
Is a victim restricted to funding & applying to courts for endless personal restraint Orders ?
Is it only the press or law enforcement able to revisit publicity onto historical perpetrators ? What does muzzling a victim do to the principle of deterrence ?
3 - How for example does a widely-notorious perpetrator prove a civil loss if "outed" to neighbours ?
An accompanying issue here might be, could “outing” by a victim be exempted partially or fully by factors like childhood victimization by crime ie one speculated a “thin-skulled victim” with non-typical vulnerability ?
Finally
- 4 - Beyond police getting such an "outing" what role if any would governancers have in some sort of a shared ownership scenario ? ( this was not such of course. ) This was arguably neighbour-level terrorism !
Yes the skillset levels of many governancers TOTALLY preclude actual "outing" being done at all by them, nor certainly without competent legal oversight ! . . 
Without such alert, just imagine unsuspectingly attempting even a minor compliance activity against the 2011 version of arsonist S.E. !
Sorting out the arsonist-outing matter judicially may not be easy.

Postscript :
Adjacency neighbourhood disputes can escalate wildly & unpredictably even in Ontario. But how often are they between total strangers ? In a notorious 2007 non-condo Pickering adjacency dispute, the senior victims of bizarre & terrifying acts of vandalism themselves were smart to sell a.s.a.p. This was platformed by their next door tormentor being jailed for a week &
then restrained by Court Order from returning to his own home for 6 months ! During the tormentor's court-ordered absence his terrified victims were able to list, sell and move 12 Km away. The trigger had been grass-cutting & boundary defiance by their next door neighbour / tormentor, who by 2014 had still not paid the half million dollars in court costs awarded to his victims !
Court heard allegations of some possible later stalking by the tormentor in his victims' new neighbourhood !
