i just wonder if you do the 1st and 2nd week and you got the stakes. Then you don't do the rest of the week but you don't remove the avatar or the signature do you still going to get those stakes?
I think it depends on the rules of specific bounty campaign.
In many cases, bounty managers clearly require that your signature must be retained until the end of the token sale period, removing the signature before that time will lead to disqualification. Then, if you remove signature, you're probably won't get any stake at all.
But, as you mentioned, you've already got stakes for 2 weeks, and if there's no stipulation otherwise, I guess you're safe with those stakes.
