There's been a sudden increase in items in this inventory, previous owners' inventory are set to private. This is possibly a storage alt.

The same guy hijacked my account last week and stole some valuable tf2 promos (earbuds etc.) thankfully steam support gave me back my items... This guy is very dangerous russian hacker...

I'm not sure what your reporting. The title shows hijacking but you've provided no proof at all to establish the fact.
