And should I say that poorbot have possibly or initially had plans to quit offering their exchange services, but were just looking for a good opportunity and something to use as an excuse? Very possible if am asked.
They don't have plans of quitting the service until they've seen the news about stopping the tipping on the platform. But anyway, with all of these speculations, anything is possible.
And as for those who kept sending tips even after poorbot have announced here and on their site that they are closing their services, I honestly fault and blame them for not being current to informations regarding a service they are using, if poorbot hadn't announced closing down their exchange service, this would have been a separate issue altogether.
This happens when the users aren't updated on what happened. Maybe those users are just too lazy to visit the service threads of poorbot and get some updates on what actually has happened.
I guess that this should be a norm for every user that actually uses any kind of service. We have to keep up to date whether they have updates or none. Just do normal checks and doing it as a practice.
