Even my information is used to sign up for other campaigns, this is really crazy
This is unfortunate situation. I have also seen my name on some spreadsheet while I wasn't participating and some I was. In such, what I do is to alert the BM and he would sort that out by removing the fake name. This not thing is getting so high these days in bounties.
This has been a problem in bounty campaign for a long time now especially in telegram and article campaign. Apart from the not entry, people manually stole other peoples work and registered it just to have token. I have also discover that it is very common with projects managed by similar persons in which all this perpetuators have succeeded earlier
