Just like 100+ other thieves, man. Get used to it.
Most thieves don't follow people around everywhere as it's a waste of time if they figured you out.
A lot of people chasing others this way aren't even thieves, they just love to grieve and harass players or get back on people who killed them or whatever.
The most satisfying steals I do with my thief are from other thieves, grievers and PK.
It doesn't happen too often unfortunately, but it's nice when it does.
Theoretically, you'd have to spawn such a topic each few hours then...
That's an optimistic view. Every few minutes is a more realistic estimate IMO.
