Same accounts - is this allowed?

I see that ‘Rocket Crates - Online’ and ‘RL Crates - Online’. Same exact descriptions, same prices and listing types, but different names for obvious reasons. Is this allowed? Both accounts make it harder to see the most recent page.

this is allowed as far as i know

Having many accounts is allowed here, you cant just abuse it for promotions etc. Also, if one account will be banned, all others as well.
