The new accounts are more susceptible to suspicion since, well, it's a new account. Euro farming is not a big deal, but the countless EXP farming can give it away. In comparison to an higher-leveled account (you legitimately played on this account for a while), it's not insanely bad, but some of those people get scrutinized for owning and what-not, thus getting reports for no reason.
TL;DR: Use them at your own risk, regardless of account.
