I also practice voting for a commenter's last post
That is a great alternative if the post is from within the last 24 hours. Not as much if it isn't, because you lose at least half of the curation rewards, or much more if it's at least 3 days old.
As for the various bot rewards, first thanks. The disadvantage is that most of them spam the blockchain and the post's comments section with needless auto-comments. Not !CTP for example.

Well, yes, I agree. Sometimes there is too much spam from such bots).
