good point with value. If i post something i always ask me the question before:

"So what? Is that valuable for my receiver or others? What impact would have that on him or her or us?"

I's human nature to fall into the trap to post something just for own enjoyment and forget that is maybe annoying for the receiver. If you put a bot on steemit only for the purpose to post senseless text snippets to random people then i say it's pure spamming and should be removed from the community as fast as possible.

Look, if someday 10 such bots starting to post senseless junk or repeatedly from one bot to the community it would be more than boring for us, it steals our time and withholds us to read valuable comments if you think that the creator of the script done that in 1 hour and now the bot steals 10s each day each receiver without any value (just the first laugh).

What is the intention of the person behind the bot? Would he like to show his programming skills or makes us more happy? That would be great but then the posts should fit in the context of the authors post and should in best case contain some value for the reader or take the topic further. Or he decide create his own blog and show something without bothering random people like in a lottery game.

When that's just the rare case and don't affects many people in a negative manner i would just ignore it. And maybe it brings in some value if somebody needs some energy or encouragement by a tiny little thing with a smile :)
