Today I received a transaction for a really tiny amount of Stella, from someone I do not know, and who appears to be bulk sending this to many people. Keybase flagged it as potentially dangerous, and I presume it is a scam of some kind, but unsure how it could work, or what I should be watching out for.

Any of you get something similar, or know what's going on? Here's a screenshot:
