Would this be considered MultiAccounting

Hello! My apologies if this isn't allowed in the sub; I haven't been here long, and this is a throwaway since I am a anxious wreck.

Upon seeing talk of a crack-down on multi-accounting, both from this thread and from a friend on a FR server, I was reminded of something that happened probably ~7 years ago when I first joined. I joined with my friend, and my younger sister after coming from PFQ on recommendations that FR was a fun game. I mention that as we swapped items for PFQ stuff, and vice versa sometimes.

The worry about multi-accounting comes from this, as me and those two regularly sent trades with large amounts of items, either as gifts or for something on PFQ (I mention this because I especially had many more gifts/unfair trades, since I was the most interested in FR) for little to nothing. This only happened during the time we we're all playing, but I'm worried because my little sister probably had the same (at that point I assume? I don't really know how IP's work) IP. This stopped when we ended up losing interest, and the two ended up never coming back. I did though, and kept my account. I haven't and never have logged onto either of the other two accounts personally, and I'm unsure if my friend or my sister has (I asked my sister about it but she didn't seem to care or remember that much, which isn't that surprising since she played for the shortest amount of time between the three of us).

I'm worried that the old crossroad records could be mistook as Multi-Accounting, and thus get my account banned, but I also didn't want to personally send a help ticket, since I really don't want to lose my account over my sister and friend trying to be nice literal years ago. Additionally, if either ever did come back, I don't want it to possibly be viewed as such. There were less then ~20 trades in total, and took place only during the time we were all active and playing separately. These are really the only details I remember, this WAS a long time ago.

Again, I'm very sorry if this is the wrong place.
