what is this - INS PROMO, VIU, XENON?

[refinement5]

Hello,

I have 3 video cards 1060 and mine some ethereum and all is fine.

But the other day i was looking at my ETH address and i noticed something strange - In the TOKENS tab i see those:

777 INS Promo
7    VIU
120 XENON

1. What are those?
2. How did i aquire them, if i only mine ethereum only?
3. Why did somebody send them to me, is there any value and is this normal?

Apologies if this is a stupid question.

thanks - one seems like a spammy promo, but the others are now worth some cents according to coingecko

May be is airdrop for ETH wallet hold and join bounty program!

i see a lot of promotions and google docs based forms circulate on social media, for so called "airdrops".
if i collect too much do they "clutter" my wallet?
how can one determine if they are listed on some exchange?
