Playing a tournament and decided to check up a guy to my left on sharkscope

His last activity is 2018 but he is sitting to my left. What does this mean?

Usually when I check people, the last activity would be the day before or sometime this year

Is this an error or just confused

He is from Portugal btw

You can opt out which is exactly what I've done. I don't need people looking up information on me to assist them or use against me.

I have no idea if past stats prior to opting out remain, or whether you can choose to delete them.

Probably opted out like the above poster said. He could also have been playing cash games since.

Also he could have taken a couple of years off and you just happened to be against him in his first tournament back. I recently came back after about 1.5 year break so it’s possible.
