I have accounts with several Trainn sites, but have only completed one. I logged into that account today and noticed that one of my referrals went red (I was already paid though, this must have happened recently). My question is...will this affect any of my other accounts?
Not sure you may want to contact TRAINN on that one.
No, it's wont. Your accounts will be fine.
It could have been that a referral frauded after he passed approval for your site..being banned from trainn for good.
