I don't think a new section is needed, just a sticky which points to these free services that all of these users are using anyway, then ban/delete all of these "post your tx and I'll accelerate it for you" posts.
"It's likely that most of these users are the same person", I was thinking the same too
while on Bitcoin Technical Support SF, some are replying with repititive copy paste info
could this be a new technique for account farmers to raise post count and rank up,
it would not be so apparent compared to how they used to post unrelated questions or replies before
There is a possibility that these accounts are owned by just one person, trying to farm accounts easily. The forum admin or moderators should definitely do something about this issue because it's nonsense to have a lot of threads offering the same service and actually using the same site to "accelerate" transactions. It's just causing a lot of spam to the forum whenever people replies to their thread asking for their transaction to be accelerated when they can even do it on their own.
