Last week I noticed that there are many users posting multiple opinions and spamming in threads. These users are often found in discussion threads mainly.
Today I found this user :-
ekoice posts his first opinion here
Definitely, price is going to cross $1000 by the end of december 2016 as we could see the price raising in a speed pace.If Bitfinex had not occured, we would have crossed $1000 by this time.

By last of this year 2016, we would definitely cross $1000.If Bitfinex had not already happened, by this time we would have crossed $1000.But Bitcoin has gained recovery from the effect of that incident.

He is not the only one and there are many more. There might be users posting multiple opinions and spamming in order to get payout from signature campaign.
I will not end this thread here but will continue to search more like them and report it here.
Also I want to put up my suggestion that discussion threads should be automatically locked after certain no. of replies or a timeframe like say 3 months or so.
