It is setup with no auth enabled and I got hammered with a spam attack +over the last weekend (predictably). What surprised me was the scale of the +attack: ikiwiki eventually triggered OOM and brought the box down. When I got +it back up, I checked out a copy of the underlying git repository, and it +measured 280M in size after being packed. Of that, about 300K was data prior +to the spam attack, so the rest was entirely spam text, compressed via git's +efficient delta compression. + +I had two thoughts about possible improvements to the comments plugin in the +wake of this: + + * comment pagination - there is a hard-to-define upper limit on the number + of comments that can be appended to a wiki page whilst the page remains + legible. It would be useful if comments could be paginated into sub-pages. + + * crude flood control - asides from spam attacks (and I am aware of + [[plugins/blogspam]]), people can crap flood or just aggressively flame + repeatedly. An interesting prevention measure might be to not let an IP + post more than 3 sequential comments to a page, or to the site, without + at least one other comment being interleaved.

Currently comments trigger the same chain of events as if the page itself had been modified (at least this seems to be the case). A way of keeping comments lightweight and out of ikiwiki would be great. This has obvious consequences but currently comments are to slow for my users. My site is complex with tags and trails (albums) so commenting the wrong page leads to several minutes of rebuild (being conservative here...). For my use case comments don't need wikilinks or any wiki features. + +To my thinking it could be useful to have comments as a very lightweight type of data that enables interactivity but not the full force of ikiwiki. Any thoughts?
