Maybe it's just the circles I run in, but I understand "tankie" to mean leftists who think Soviet/Maoist/vanguard-party styles of Communist revolution/rule were good, actually, to the point of denying any bad things they did/do as "Western propaganda".

Given the red scare in the US, our ability as a whole to use any sort of leftist political labels accurately across the population is basically non-existent, so I do understand the frustration by both tankies and non-tankie leftists about how the term gets used lately, especially in produce circles on social media.

But again maybe that's just me. I don't know if I would consider myself a communist, but I do consider myself as a yet undetermined variety of socialist, if that helps at all.
