I've heard it a lot of times, but fortunately, I've never experienced this myself. IIRC, this is caused by the attraction system, where other Sims that are attracted to your Sim will send you love letters and gifts. However, the feature is a bit buggy, and if the giver is a townie / not present at the home world at the moment, the letters and gifts will be glitched and it will show up as omni plants and bills. I'm pretty sure I've read it somewhere, but I really forgot where it was; chances are it's from either MTS or MATY. The workaround is to either use Twallan's mods, if I'm not mistaken, to avoid this attraction gift situation? I don't really remember.
