very appropriate if you do not receive a gift because all the consequences and rules are clear on the gift of the site you are following, if you remove the signature, you can notify the management of the gift you are following by telegram or other communication
Gift? you mean to say that it's the bounty or reward correct? understand the importance of knowing the rules of the bounty that you are about to join. And if you joined without understanding the rules of the bounty, it's your problem.
Even notifying them won't help unless it's stated that they have the right to do so whenever a participant removed their signature. Pleading them won't especially if they are strict with their rules.
Rules should really be strictly followed and its been stated before the campaign start.If its been said to equip signature until the end the campaign then you should follow it.
Decision would vary with the manager if he would consider out to count stakes for those who leave and plan to join other campaigns but most of the time the dont really grant such request.
