For config-based spamfilters, the reason was not escaped, meaning that
spaces and underscores did not work as expected.
For example, in "STATS spamfilter" the spaces were displayed as-is
which means that the numeric output was not really parsable.
Apparently this bug exists since UnrealIRCd 5 already...
For example, because of a different version of PCRE2, or because of the switch
from non-UTF8 to UTF8 (or vice versa) which disallows certain byte sequences.
This happens when !, || or && are used, though the exact requirements
for the crash may also require a function with arguments.

when they are only in channel(s) with very low member counts.
This because some typical bot/drone behavior is not to join any channels.
This kinda forces them to expose themselves a bit more (and if they don't,
they don't get more reputation).
The downside is for the unusual case where a legit chatter would be on
the network but not joining any channels, but that is rare. In any case,
this setting can be adjusted if that is typical or more normal behavior
on your network :D.
* The [reputation score](https://www.unrealircd.org/docs/Reputation_score)
of connected users (actually IP's) is increased every 5 minutes. We still
do this, but only for users who are at least in one channel that has 3
or more members. This setting is tweakable via
[set::reputation::score-bump-timer-minimum-channel-members](https://www.unrealircd.org/docs/Set_block#set::reputation).
Setting this to 0 means to bump scores also for people who are in no
channels at all, which was the behavior in previous UnrealIRCd versions.
action { set REPUTATION--; } and similar.
Also enhancement to reputation S2S traffic, to support decreasing:
*
+ * Since UnrealIRCd 6.0.2+ there is now also asterisk-score-asterisk:
+ * :server REPUTATION 1.2.3.4 *2*
+ * The leading asterisk means no reply will be sent back, ever, and the
+ * trailing asterisk will mean it is a "FORCED SET", which means that
+ * servers should set the reputation to that value, even if it is lower.
+ * This way reputation can be reduced and the reducation can be synced
+ * across servers, which was not possible before 6.0.2.
+ *
So if you are actually decreasing reputation, you need all servers on
6.0.2 or higher for it to work properly, otherwise the other servers
don't decrease it, and next connect the highest wins again, etc.
even when multiple modules were upgraded.
Actually not sure about the cause and how this is possible, but running
'make install' only once at the end is the solution, which is something
that should be done that way anyway.

In the config file, when not using quotes, a slash at the beginning of a
variable name or value was silently discarded (eg `file /tmp/xyz;` resulted
in a file `tmp/xyz`).
