The TC badge isn't permanent. You have to answer questions continually in a category to have a CHANCE of keeping it or gaining one. The chance depends on other users' performances in the category as well (and whatever other factors that Yahoo has hidden up its sleeve or software). You can be TC in an obscure category that has few questions...the factors are variable, so that's why there's no exact formula known by an user for sure. Answering questions helps; earning best answers helps; being active in specific categories helps; and outperforming others helps.

Top Contributor badge is given for regularity of participation to a unique volume. This is to encourage answerers to stay connected to Y!A which Yahoo is doing for his or her possess curiosity.

But within the variety of questions you ask, BA isn't the only favored via such a lot readers, however person who satisfies the asker and asker's prerogative has bought to be revered.
