That Steam ID is mine, is SA trying to kick me?

I'm getting this every time a player joins 

"

I ended by removing this thing, Steam checks does the same thing and doesn't conflict with other plugins like Admin Deep Cover.

Serverarmour doesn't conflict with admin deep cover. Never has. You are refering to a bug that was present in ADC itself. See below:
