Yahoo suggested not to have a new topic for every group, they suspect but seems they never listen and just started another
topic today.
You also don't need a separate thread for each group you are finding as alts. Make a thread like Timelords or report in his thread. No need to make 1000 different threads.
And, spamming on my trust page.
I do not know how non-alt accounts enrolling a same campaign can be unethical.
