"but the purpose of using voting bots is to promote your post so that it shows higher in the categories for which it's tagged" 

I do not use them for this purpose. I do not think anyone is searching by tags around here if anyone searches at all.

My purposes in using the bots are:
- increase the reward for my real voters
- increase my sp
- increase my payouts

So I always hope they are profitable.

I cannot see you or steemnow today. It may by my fault because I am in Myanmar, but I am letting you know just in case there is a problem on your end.
