Lately it seems that getting members to join signature bounties became very hard till almost impossible. Hugh amounts joining social-networks bounties tho.
Are the big numbers of upcoming icos the reason?
OR what else could it be?
I think the big numbe rof ico coming up is the valid reason, one signature campaign usually last two to three months to last so any new signature campaign coming up will have a hard to get new campaigner because some of the members are into other signature campaign a member usually, look immediately for a new campaign the moment they are allowed to take out the signature campaign.
