Is it OK to spam hundreds of times in Yahoo Answers if I also give a reasonable answer?

IT IS OKAY TO GIVE THE SAME ANWSER repeatedly, if it answers the question. I've seen certain high points members on this venue do so, as when they paste a passage, verbatim, from the Community Guidelines on here as their answer to questions about chatting....and they do so over and over and over to every question of this nature. I frequently also give the same response in defense of a less stringent application of the chatting rules, albeit in a slightly varied form.

However, what you're describing IS still a violation of the Community Guidelines, where under the section "Exploiting The Community" it says "...It is not OK to post links...that are...clearly meant only to solicit others for personal and financial gain." Even if the responders you are complaining about are not posting actual links, they are clearly soliciting for financial gain, which can be reasonably interpreted as a violation of this particular guideline, and could be reported for spam.

these are spmabots and they should ALL be reported not only for spamming but also for the fact that telling people to "google it" is not a valid answer either

It is not ok and all as described should be reported.
