Last days i notice a strange groups wandering around in mines. They are usually 2-3-5...x in count. It seems that one leads and other just follow it. When first stop and start to mine all others do the same. I suppose they use follow feature, but i'm not so sure what it is exactly.
Such groups mine all in their way - usually sparkly and beryl.
If it is possible to mine fast in group using "follow" feature i think this is unfair and something like abuse of this feature. It is like first one got a free bots which mine for him.
I'm still not so sure what exactly happens and how. If this are legitimate player groups it is ok. But if it is not - well i do not think this is fair.
