How long is it until something is considered secure?

[Azn]

I would say 1 month but then again, it depends on how the account was frozen.
If it's suspicious activity or falling for a scam or something, I would wait a while longer.

[Austin]

For the top sellers its normally 1+month

[AstraCastra]

I used to trade UC pets frequently and 3 months was the norm amongst decent traders and everything under that was considered shady

[gudboy]

do plundered account mostly get returned?

[DarkAngel]

Agreed with Katia, 2 months

[Kylae]

Yes, plundered accounts do get returned, and it's at that point that they go hunting for the items, Ie, about two months later, so make sure everything's well moved before then.

[Mikey]

6 months +
