Hijacking a thread should be an Infractable Offence?

[SLiZZaRD]

The rule could be somewhere along the lines of:

Do not post questions or problems on someone else's thread and interrupt a topic of discussion.

An example of an extreme case of the matter:
In the forum "Homework Help"
OP posts asking for math help, someone else posts asking for English help etc.

It's annoying when someone veers the topic to something completely different.

It is infractable.
