It is, and will continue to be until a rule is made against it, a viable strategy for netting in FFA. Frankly, if you don't like it, you're probably in the wrong server. It is not only not going away, it is becoming more prevalent and more accepted, with 4 of the 6 largest clans on the server allowing it (I think only KA and NBK do not).

It's what it takes to be competitive in netting here, and is the only way you can really hope for a top 100.

Self farming and treatment of 1 man tags are 2 completely different matters imo though.
