I also thought it might have been just 0 points, but his other comment in the thread still appears as [dead] for me. jacko0's comment now appears as normal, although earlier I clearly remember it was [dead]. icecreampain's still appears as [dead]. Anyway, it could be some glitch in the software, but the system is a bit strange anyway.
a bit strange anyway is the best description I can muster too. however it does not send me emails nor try to get my kids to buy upgrades of dubious worth. so on balance it beats out most other things on an iPhone :-)
(sorry very annoyed by kids games that chuck in upgrades and unlocks fr cash - really really unacceptable)
However your comments seem fine from where I'm standing - possibly someone mistook 0 points for banned/dead?
And yes - loving seeing parts of London I know so well.
