Easiest for me:
1 go thru the first 50 pages of altcoin announcements.
2 put all the ANN profiles on ignore. Takes about 3 days. usually they make a brand new account anyways, so you're not missing out on anything.
3 when you hear something interesting about the coin, take the account off of ignore
4 you're left with 49 pages of grey announcements, and one with blue ones
5 every time you log in, you get about 5-10 new announcements that are easy to spot. put those profiles on ignore unless it seems really cool (in your case, not ipo).
6 repeat
7 ?
8 profit of course. bonus points for going through 100+ pages of alt announcements, and combining steps 2 and 3.
Of course, this is just a passive resistance method. You seem to be looking to take an active one.
Is it possible to make a script to do this? Maybe someone could make one that just puts all those profiles on ignore?
What do you mean with ANN profiles?
