Your absolutely right, and its so easy to get sucked in, and so hard to do what we all know we shouldn't - 'feed the trolls'. However on the plus side - other platforms have got the 'hate speech, troll' regulations so tight, your afraid to even write words in case you break the TOS. Steemit at least is not this way - yet, however a 'block/mute' function would be welcome, we should at least have personal control over our blog access.
