Quoted from TigerLaw:No it does not. We understand some people log in from the same location from time to time.
Yes, for example my husband and I have seperate accounts but work together and of course will show in the same IP at home, so we have multiple duplicate IPs. We mods do quite a bit of research before banning anyone as a duplicate, and even then we've made a mistake or two and fixed it, but on the whole we try hard to be fair and understanding. Most spam is obvious and quickly taken care of, but there has been an increasing number lately.
