British accents are very regional and varied. You can pinpoint somebody pretty accurately geographically by their accent here. I may be totally wrong but it may help to imagine Actors/musicians/celebrities from that region to understand how different each British Poster probably sounds. I have no idea but here are some guesses
@Greenbeanz - Westcountry -A Pirate like Robert Newton as Long John Silver
@Memphis -Bristol ? - Westcountry - Blackbeard
@Fenster - Cockney -a very pissed and cynical Michael Caine/Ray Winstone
@smashup - Cockney -Danny Dyer
@superheavyrhun -Mid/South Wales ? -Nicky Wire (Manic Street Preachers)
@Dia bando -North Wales - Windsor Davies/Enzo Calzaghe
@Vendettos -Scottish - Glaswegian? -Rab C Nesbitt / Billy Connolly
@Master -Midlands - Noddy Holder (Slade)/Jasper Carrott
@Gandalf -Harrogate ? - Brian Sewell/Stewie from Family Guy
@Cressa121 -Sunderland -Tony Jeffries -Boxer
@Dark Lord Al -Hell -Christopher Lee -Saruman
