You're right they can regain the trust sooner than our expectations because they haven't done much damage to the community but they will still have to prove that they won't be inactive and they'll offer those features for long term. The community is always ready to welcome a project's comeback and they'll accept the comeback of Bitvest with open arms.
If I'm not wrong here as I don't much follow what happened to them before the only mistake they made is the payment delay of their campaign participants before. If this is the case then for sure they can regain back their reputation since they are now running a campaign which can be a good start for them. Also if lightlord can show that those issues will not happen anymore then for that people could see their relevance. Maybe there are still people doubting for their return but if Bitvest can show how eager they are for regaining their reputation back also they have good concern with there campaign participants then all of their issue from the pass might be erased our from the mind of people. For now its good to see that they are doing really great and so far all of people participating on any activities to them are in great shape.
Basically there were 3 main issues happened in the past 1Delayed payment 2LL's inactivity due to health issues and 3Slow refill when hot wallet empty.
Fortunately LL has came back, relaunch the campaign and hopefully he is now doing good so there will be no more issues especially related to hotwallet because it is related to his players.
Still LL needs someone or some people to back up when he has something important IRL that make him unable to manage his site well.
There was Zodiac (his friend IIRC) who helped him to manage his project, not really sure if he is still here to help LL but it will be better to have some more guys he trusts to help him.
