So...i've left the comment active on the forums post, but this is probably the 5th time i've seen this exact comment about dissertation writers, all from different IPs, so coming to the obvious conclusion that they are spambots, what's the next step.

1) Remove the comment(s) as they appear and do nothing

2) Remove the comment(s) and close the forum in question, then do nothing

3) Remove the comment(s), close the forum and block the account permanently to prevent future spamming potential

4) Present an alternate solution in the comments
