1) If you have no intentions of showing yourself on the boards, then I think just looking for inactive pets is fine for you. A lot of people want PC safe pets so they can trade it again without garnering too much suspicion, but I personally think it is unsafe to be trading illegitimate pets (any pet that is sold is considered illegitimate) regardless of it being PC safe or not. It's ALWAYS better to buy the pet you want directly and to settle down. OR if you do insist on trading, make sure your account looks good enough to house the kind of pet you want (e.g. you would want a well-built account to keep a high tier pet) and STAY OFF THE BOARDS! Neomailing is the way to go, but do it in moderation.
But if anything, you should definitely consider trading on the UC swap thread we have on cK if you really want to trade for a different pet. It's not impossible to fit in on the PC, but it is extremely difficult. The downside to PC safe pets is that some people actually
stalk pets or carefully monitor them. You would also be amazed at how strong some people's memories are!
2) I will personally PM you about this, but very openly speaking, my go-to people would definitely be @
(you need an account to see links), @
(you need an account to see links) and @
(you need an account to see links). Each of these sellers have a huge stock, fair prices and are notorious for selling you safe and inactive pets.
Fair warning, there ARE people who may sell you active pets that are advertised as inactive, so please stick to people you
trust.
3) No, it does not set off a radar for TNT. It will for other users if you show yourself on the boards. ALSO, adding on to my point earlier - some people WILL stalk known UCs, so PC safe pets are not always the way to go.
One thing to keep in mind is that if you ever receive the account the pet is on when you buy a UC,
USE A VPN and CLEAR YOUR COOKIES before accessing other accounts. I've gotten chained for not clearing my cookies multiple times. Ever since I got in the habit of religiously using Google Incognito and a VPN for logging into new accounts, I haven't been frozen yet, which is amazing since I've accessed maybe anywhere upwards of a hundred different accounts in the past four months.
