Which site is that? It seems fun.
mempool.space
It has quite some interesting features if one has time to play with it, including animation.
That are your campaign paymets? In that case is not possible to accelerate them 
Yes, they are. I tried viaBTC but it always exists the size limit unfortunately. I wanted to check their paid service but it seems for their paid service for each a transaction they charge over $200 LOL. I don't see no point to spend that much.Yep, ViaBTC would have been a good lifeboat if the tx would have been smaller. Maybe you consider making smaller batches in the future (just an idea).
Any chance for people to start doing CPFP for some of those transactions? (Probably not, unless they are getting desperate).
All transaction texts are saved now and in the case of a dropped transaction, I can rebroadcast it.
In the past two weeks the mempool got more and more congested.
You may have to make another (probably multisig) wallet for handling the payments until your current ones are getting confirmed or dropped. (I am aware that this can cause funding issues. I'm just saying; you do as you think it's best.)
